getsid(2)                  System Calls Manual                 getsid(2)

ИМЯ

       getsid - get session ID

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <unistd.h>

       pid_t getsid(pid_t pid);

   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       getsid():
           _XOPEN_SOURCE >= 500
               || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L

ОПИСАНИЕ

       getsid() returns the session ID of the process with process ID
       pid.  If pid is 0, getsid() returns the session ID of the calling
       process.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, a session ID is returned.  On error, (pid_t) -1 is
       returned, and errno is set to indicate the error.

ОШИБКИ

       EPERM  A process with process ID pid exists, but it is not in the
              same session as the calling process, and the
              implementation considers this an error.

       ESRCH  No process with process ID pid was found.

ВЕРСИИ

       Linux does not return EPERM.

СТАНДАРТЫ

       POSIX.1-2008.

ИСТОРИЯ

       POSIX.1-2001, SVr4.  Linux 2.0.

ПРИМЕЧАНИЯ

       See credentials(7) for a description of sessions and session IDs.
