GETSID(2) Linux Programmer's Manual GETSID(2) NAME
getsid - get session ID SYNOPSIS
#include <unistd.h> pid_t getsid(pid_t pid); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): getsid(): _XOPEN_SOURCE >= 500 DESCRIPTION
getsid(0) returns the session ID of the calling process. getsid(p) returns the session ID of the process with process ID p. (The session ID of a process is the process group ID of the session leader.) RETURN VALUE
On success, a session ID is returned. On error, (pid_t) -1 will be returned, and errno is set appropriately. ERRORS
EPERM A process with process ID p 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 p was found. VERSIONS
This system call is available on Linux since version 2.0. CONFORMING TO
SVr4, POSIX.1-2001. NOTES
Linux does not return EPERM. SEE ALSO
