PLWP_GETPSINFO(3PROC) Process Control Library Functions PLWP_GETPSINFO(3PROC)

NAME

Plwp_getpsinfo - get thread specific ps information

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

int
Plwp_getpsinfo(struct ps_prochandle *P, lwpid_t lwpid, lwpsinfo_t *lps);

DESCRIPTION

The Plwp_getpsinfo() function looks up the thread-specific ps(1)
information for the thread specified by lwpid in the process handle P. The
caller should provide a pointer to an lwpsinfo_t, lps, whose definition can
be found in proc(5). lps will be filled in with information such as the
thread's id, its current state, priority, and run-time.

The Plwp_getpsinfo() function only works on process handles that refer to
active processes and core files, it does not work on process handles that
refer to individual files.

RETURN VALUES

Upon successful completion, the Plwp_getpsinfo() function returns 0 and lps
is filled in with the thread-specific ps(1) information. Otherwise, -1 is
returned and errno is set to indicate the error.

ERRORS

For a full list of possible errors also see the DIAGNOSTICS section in
proc(5).

The Plwp_getpsinfo() function will fail if:

ENODATA P refers to a file handle obtained through
Pgrab_file(3PROC).

EINVAL The process handle P refers to a core file and the
specified thread does not exist.

ENOENT The process handle P refers to an active process and the
specified thread does not exist.
