PR_SET_NAME(2const)                                  PR_SET_NAME(2const)

ИМЯ

       PR_SET_NAME, PR_GET_NAME - operations on a process or thread

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #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]);

ОПИСАНИЕ

       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).

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

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

ОШИБКИ

       EFAULT name is an invalid address.

ФАЙЛЫ

       /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).

СТАНДАРТЫ

       Linux.
