Profiler

This is an engine profiler hook extension. It supports three processing modes.

Modes

• Function timing profiler: use SGS_PROF_FUNCTIME to initialize
• Instruction timing profiler: use SGS_PROF_OPTIME to initialize
• Memory usage profiler: use SGS_PROF_MEMUSAGE to initialize

Functions

• void sgs_ProfInit( sgs_Context* C, sgs_Prof* P, int mode ) - initialize the profiler
• void sgs_ProfClose( sgs_Prof* P ) - free the profiler
• void sgs_ProfDump( sgs_Prof* P ) - dump the data

Usage example

sgs_Prof profiler; // keep this allocated while it is linked to engine
// initialize and attach the profiler
sgs_ProfInit( contextPtr, &profiler, [SGS_PROF_FUNCTIME|SGS_PROF_OPTIME|SGS_PROF_MEMUSAGE] );
// ...do things with the engine...
sgs_ProfDump( &profiler ); // dump the data (done through @sgs_Write* functions)
// free the profiler - must be done before freeing the engine
sgs_ProfClose( &profiler );
