NAME

       PR_SET_NAME, PR_GET_NAME - operations on a process or thread

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <linux/prctl.h>  /* Definition of PR_* constants */
       #include <sys/prctl.h>

       int prctl(PR_SET_NAME, char name[16]);
       int prctl(PR_GET_NAME, const char name[16]);

DESCRIPTION

       PR_SET_NAME
              Set  the  name of the calling thread, using the value in the location pointed to by
              name.

              The name can be up to 16 bytes long, including the terminating null byte.   If  the
              length  of  the  string, including the terminating null byte, exceeds 16 bytes, the
              string is silently truncated.

       PR_GET_NAME (since Linux 2.6.11)
              Return the name of the calling thread, in the  buffer  pointed  to  by  name.   The
              returned string will be null-terminated.

       This  is  the same attribute that can be set via pthread_setname_np(3) and retrieved using
       pthread_getname_np(3).

RETURN VALUE

       On success, 0 is returned.  On error, -1 is returned, and errno is  set  to  indicate  the
       error.

ERRORS

       EFAULT name is an invalid address.

FILES

       /proc/self/task/tid/comm
              The  attribute  is  likewise accessible via this file (see proc_pid_comm(5)), where
              tid is the thread ID of the calling thread, as returned by gettid(2).

STANDARDS

       Linux.
