sys_getrusage [kernel/sys.c]
Gets current resource usage. Arguments
eax | 77
ebx | It must be one of the following values:
`RUSAGE_SELF - get resource usage for parent process RUSAGE_CHILDREN - get resource usage for child processes.`
ecx | Pointer to a rusage structure which will be filed with return information:
`struc rusage {``.ru_utime timeval ; user time used .ru_stime timeval ; system time used .ru_maxrss rd 1 ; maximum resident set size .ru_ixrss rd 1 ; integral shared memory size .ru_idrss rd 1 ; integral unshared data size .ru_isrss rd 1 ; integral unshared stack size .ru_minflt rd 1 ; page reclaims .ru_majflt rd 1 ; page faults .ru_nswap rd 1 ; swaps .ru_inblock rd 1 ; block input operations .ru_oublock rd 1 ; block output operations .ru_msgsnd rd 1 ; messages sent .ru_msgrcv rd 1 ; messages received .ru_nsignals rd 1 ; signals received .ru_nvcsw rd 1 ; voluntary context switches .ru_nivcsw rd 1 ; involuntary context switches } struc timeval { tv_sec rd 1 ; seconds tv_usec rd 1 ; microseconds }`
Return values If the system call succeeds the return value is 0. If the system call fails the return value is one of the following errno values:
`-EINVAL` | `ebx is invalid.`
`-EFAULT` | `ecx points outside the accessible address space.`
Remarks In Linux kernel versions before 2.6.9, if the disposition of SIGCHLD is set to SIG_IGN then the resource usages of child processes are automatically included in the value returned by RUSAGE_CHILDREN. Compatibility n/a
