    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 corresponding 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 contain the correct number of seconds.
