getrusage - Gets the current resource usages
Manual
Code Examples

getrusage( [int$mode = 0] ): array|false

This is an interface to getrusage(2). It gets data returned from the system call.

Parameters

mode

If mode is 1, getrusage will be called with RUSAGE_CHILDREN.

Return Values

Returns an associative array containing the data returned from the system call. All entries are accessible by using their documented field names. Returns false on failure.

Notes

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 mode is RUSAGE_SELF) "ru_maxrss" (only if mode is RUSAGE_SELF)

If getrusage is called with mode 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"
