Macro Definition Documentation

#define PFS_MAX_FULL_PREFIX_NAME_LENGTH   32

Maximum length of the 'full' prefix of an instrument name. For example, for the instrument name 'wait/sync/mutex/sql/LOCK_open', the full prefix is 'wait/sync/mutex/sql/', which in turn derives from a prefix 'wait/sync/mutex' for mutexes, and a category of 'sql' for mutexes of the sql layer in the server.

Definition at line 42 of file pfs_instr_class.h.

#define PFS_MAX_INFO_NAME_LENGTH   128

Maximum length of an instrument name. For example, 'wait/sync/mutex/sql/LOCK_open' is an instrument name.
