Parameters

col_meta	column meta data
p1	key p1_len key length
p2	second key
p2_len	second key length

Returns: 1, 0, -1, if a is greater, equal, less than b, respectively

Definition at line 426 of file api0api.h.

typedef struct ib_cursor_t* ib_crsr_t

InnoDB cursor handle

Definition at line 413 of file api0api.h.

typedef enum dberr_t ib_err_t

All InnoDB error codes are represented by ib_err_t

Definition at line 52 of file api0api.h.

typedef int16_t ib_i16_t

A signed 16 bit integral type.

Definition at line 86 of file api0api.h.

typedef int32_t ib_i32_t

A signed 32 bit integral type.

Definition at line 102 of file api0api.h.

typedef int64_t ib_i64_t

A signed 64 bit integral type.

Definition at line 118 of file api0api.h.

A signed 8 bit integral type.

Definition at line 70 of file api0api.h.

typedef int(* ib_msg_log_t)(ib_msg_stream_t, const char *,...)

All log messages are written to this function.It should have the same

behavior as fprintf(3).

Definition at line 389 of file api0api.h.

typedef FILE* ib_msg_stream_t

The first argument to the InnoDB message logging function. By default

it's set to stderr. You should treat ib_msg_stream_t as a void*, since it will probably change in the future.

Definition at line 385 of file api0api.h.

typedef struct ib_tuple_t* ib_tpl_t

InnoDB tuple handle. This handle can refer to either a cluster index

tuple or a secondary index tuple. There are two types of tuples for each type of index, making a total of four types of tuple handles. There is a tuple for reading the entire row contents and another for searching on the index key.

Definition at line 401 of file api0api.h.

typedef struct trx_t* ib_trx_t

InnoDB transaction handle, all database operations need to be covered

by transactions. This handle represents a transaction. The handle can be created with ib_trx_begin(), you commit your changes with ib_trx_commit() and undo your changes using ib_trx_rollback(). If the InnoDB deadlock monitor rolls back the transaction then you need to free the transaction using the function ib_trx_release(). You can query the state of an InnoDB transaction by calling ib_trx_state().

Enumeration Type Documentation

enum ib_cfg_type_t

Possible types for a configuration variable.

Enumerator:

IB_CFG_ULINT	The configuration parameter is of type ulint
IB_CFG_ULONG	The configuration parameter is of type ulong
IB_CFG_TEXT	The configuration parameter is of type char*
IB_CFG_CB	The configuration parameter is a callback parameter

Definition at line 135 of file api0api.h.

enum ib_col_attr_t

InnoDB column attributes

Enumerator:

IB_COL_NONE	No special attributes.
IB_COL_NOT_NULL	Column data can't be NULL.
IB_COL_UNSIGNED	Column is IB_INT and unsigned.
IB_COL_NOT_USED	Future use, reserved.
IB_COL_CUSTOM1	Custom precision type, this is a bit that is ignored by InnoDB and so can be set and queried by users.
IB_COL_CUSTOM2	Custom precision type, this is a bit that is ignored by InnoDB and so can be set and queried by users.
IB_COL_CUSTOM3	Custom precision type, this is a bit that is ignored by InnoDB and so can be set and queried by users.

Definition at line 227 of file api0api.h.

enum ib_col_type_t

column types that are supported.

Enumerator:

IB_VARCHAR	Character varying length. The column is not padded.
IB_CHAR	Fixed length character string. The column is padded to the right.
IB_BINARY	Fixed length binary, similar to IB_CHAR but the column is not padded to the right.
IB_VARBINARY	Variable length binary
IB_BLOB	Binary large object, or a TEXT type
IB_INT	Integer: can be any size from 1 - 8 bytes. If the size is 1, 2, 4 and 8 bytes then you can use the typed read and write functions. For other sizes you will need to use the ib_col_get_value() function and do the conversion yourself.
IB_SYS	System column, this column can be one of DATA_TRX_ID, DATA_ROLL_PTR or DATA_ROW_ID.
IB_FLOAT	C (float) floating point value.
IB_DECIMAL	C (double) floating point value. Decimal stored as an ASCII string
IB_VARCHAR_ANYCHARSET	Any charset, varying length
IB_CHAR_ANYCHARSET	Any charset, fixed length

Definition at line 165 of file api0api.h.

enum ib_index_type_t

Enumerator:

IB_CLUSTERED	clustered index
IB_UNIQUE	unique index

Definition at line 272 of file api0api.h.

enum ib_lck_mode_t

InnoDB lock modes.

Enumerator:

IB_LOCK_IS	Intention shared, an intention lock should be used to lock tables
IB_LOCK_IX	Intention exclusive, an intention lock should be used to lock tables
IB_LOCK_S	Shared locks should be used to lock rows
IB_LOCK_X	Exclusive locks should be used to lock rows
IB_LOCK_TABLE_X	exclusive table lock
IB_LOCK_NONE	This is used internally to note consistent read
IB_LOCK_NUM	number of lock modes

Definition at line 251 of file api0api.h.

enum ib_match_mode_t

Various match modes used by ib_cursor_moveto()

Enumerator:

IB_CLOSEST_MATCH	Closest match possible
IB_EXACT_MATCH	Search using a complete key value
IB_EXACT_PREFIX	Search using a key prefix which must match to rows: the prefix may contain an incomplete field (the last field in prefix may be just a prefix of a fixed length column)

Definition at line 300 of file api0api.h.

enum ib_srch_mode_t

 InnoDB cursor search modes for ib_cursor_moveto().

Note: Values must match those found in page0cur.h

Enumerator:

IB_CUR_G	If search key is not found then position the cursor on the row that is greater than the search key
IB_CUR_GE	If the search key not found then position the cursor on the row that is greater than or equal to the search key
IB_CUR_L	If search key is not found then position the cursor on the row that is less than the search key
IB_CUR_LE	If search key is not found then position the cursor on the row that is less than or equal to the search key

Definition at line 279 of file api0api.h.

enum ib_tbl_fmt_t

InnoDB table format types

Enumerator:

IB_TBL_REDUNDANT	Redundant row format, the column type and length is stored in the row.
IB_TBL_COMPACT	Compact row format, the column type is not stored in the row. The length is stored in the row but the storage format uses a compact format to store the length of the column data and record data storage format also uses less storage.
IB_TBL_DYNAMIC	Compact row format. BLOB prefixes are not stored in the clustered index
IB_TBL_COMPRESSED	Similar to dynamic format but with pages compressed

Definition at line 207 of file api0api.h.

enum ib_trx_level_t

Transaction isolation levels

Enumerator:

IB_TRX_READ_UNCOMMITTED	Dirty read: non-locking SELECTs are performed so that we do not look at a possible earlier version of a record; thus they are not 'consistent' reads under this isolation level; otherwise like level 2
IB_TRX_READ_COMMITTED	Somewhat Oracle-like isolation, except that in range UPDATE and DELETE we must block phantom rows with next-key locks; SELECT ... FOR UPDATE and ... LOCK IN SHARE MODE only lock the index records, NOT the gaps before them, and thus allow free inserting; each consistent read reads its own snapshot
IB_TRX_REPEATABLE_READ	All consistent reads in the same trx read the same snapshot; full next-key locking used in locking reads to block insertions into gaps
IB_TRX_SERIALIZABLE	All plain SELECTs are converted to LOCK IN SHARE MODE reads

Definition at line 348 of file api0api.h.

enum ib_trx_state_t

 The transaction state can be queried using the

ib_trx_state() function. The InnoDB deadlock monitor can roll back a transaction and users should be prepared for this, especially where there is high contention. The way to determine the state of the transaction is to query it's state and check.

Enumerator:

IB_TRX_NOT_STARTED	Has not started yet, the transaction has not ben started yet.
IB_TRX_ACTIVE	The transaction is currently active and needs to be either committed or rolled back.
IB_TRX_COMMITTED_IN_MEMORY	Not committed to disk yet
IB_TRX_PREPARED	Support for 2PC/XA

Definition at line 333 of file api0api.h.
