Function Documentation

void __mcount (  unsigned int  frompc, unsigned int  selfpc )

Internal C handler for _mcount(). Parameters: frompc  pc address of caller selfpc  pc address of current function Called from mcount.S to make life a bit easier. __mcount is called right before a function starts. GCC generates a tiny stub at the very beginning of each compiled routine, which eventually brings the control to here.

void gprof_cleanup (   )

Writes gmon.out dump file and stops profiling. Called from atexit() handler; will dump out a host:gmon.out file with all collected information.
