__attribute__

struct UsbDriver __attribute__

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

Stop the profiler.

Internal timer handler.

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.

If the profiler is not running, this function does nothing.

Parameters

filename	The name of the file to write the profiling data to.
should_dump	If 1, the profiling data will be written to the file. If 0, the profiling data will be discarded.

s_addr

in_addr_t s_addr
