#define PSI_CURRENT_STAGE_VERSION 1 |
Performance Schema Stage Interface number for the most recent version.
The most current version is PSI_STAGE_VERSION_1
#define PSI_STAGE_VERSION_1 1 |
Performance Schema Stage Interface number for version 1.
This version is supported.
typedef void(* end_stage_v1_t) (void) |
End the current stage.
typedef PSI_stage_progress_v1 *(* get_current_stage_progress_v1_t) (void) |

typedef struct PSI_stage_info_v1 PSI_stage_info |
typedef struct PSI_stage_info_v1 PSI_stage_info_v1 |
typedef unsigned int PSI_stage_key |
Instrumented stage key.
To instrument a stage, a stage key must be obtained using register_stage
. Using a zero key always disable the instrumentation.
