7.0.0	This function is now supported on Windows.

주의

Note:
On Windows getrusage() will only return the following members:

"ru_stime.tv_sec"

"ru_stime.tv_usec"

"ru_utime.tv_sec"

"ru_utime.tv_usec"

"ru_majflt" (only if who is RUSAGE_SELF)

"ru_maxrss" (only if who is RUSAGE_SELF)

If getrusage() is called with who set to 1 (RUSAGE_CHILDREN), then resource usage for threads are collected (meaning that internally the function is called with RUSAGE_THREAD).

Note:
on BeOS 2000, only the following members are returned:

"ru_stime.tv_sec"

"ru_stime.tv_usec"

"ru_utime.tv_sec"

"ru_utime.tv_usec"
