_lwp_info(2) System Calls _lwp_info(2)NAME_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 the lwpinfo structure pointed to by
buffer with time-accounting information pertaining to the calling LWP.
This call may be extended in the future to return other information to
the lwpinfo structure as needed. The lwpinfo structure in
<sys/lwp.h> includes the following members:
timestruc_t lwp_utime;
timestruc_t lwp_stime;
The lwp_utime member is the CPU time used while executing instructions
in the user space of the calling LWP.
The lwp_stime member is the CPU time used by the system on behalf of
the calling LWP.
RETURN VALUES
Upon successful completion, _lwp_info() returns 0 and fills in the
lwpinfo structure pointed to by buffer.
ERRORS
If the following condition is detected, _lwp_info() returns the corre‐
sponding value:
EFAULT The buffer argument points to an illegal address.
Additionally, the _lwp_info() function will fail for 32-bit interfaces
if:
EOVERFLOW The size of the tv_sec member of the timestruc_t type
pointed to by lwp_utime and lwp_stime is too small to con‐
tain the correct number of seconds.
