_lwp_info

- return the time-accounting information of a single LWP

Synopsis

#include <sys/time.h>#include <sys/lwp.h>int_lwp_info(struct lwpinfo *buffer);

Description

The_lwp_info() function fills thelwpinfo structure pointed to bybuffer with time-accounting information pertaining to the calling LWP. This call maybe extended in the future to return other information to thelwpinfostructure as needed. Thelwpinfo structure in <sys/lwp.h> includesthe following members:

timestruc_t   lwp_utime;timestruc_t   lwp_stime;

Thelwp_utime member is the CPU time used while executing instructions inthe user space of the calling LWP.

Thelwp_stime member is the CPU time used by the system onbehalf of the calling LWP.

Return Values

Upon successful completion,_lwp_info() returns0 and fills in thelwpinfo structure pointed to bybuffer.

Errors

If the following condition is detected,_lwp_info() returns the corresponding value:

EFAULT

Thebuffer argument points to an illegal address.

Additionally, the_lwp_info() function will fail for 32-bit interfaces if:

EOVERFLOW

The size of thetv_sec member of thetimestruc_t type pointed to bylwp_utime andlwp_stime is too small to contain the correct number of seconds.
