SETSID(2)			     BSD System Calls Manual				SETSID(2)

     setsid -- create session and set process group ID

     Standard C Library (libc, -lc)

     #include <unistd.h>


     The setsid() function creates a new session.  The calling process is the session leader of
     the new session, is the process group leader of a new process group and has no controlling
     terminal.	The calling process is the only process in either the session or the process

     Upon successful completion, the setsid() function returns the value of the process group ID
     of the new process group, which is the same as the process ID of the calling process.

     If an error occurs, setsid() returns -1 and the global variable errno is set to indicate the
     error, as follows:

     [EPERM]		The calling process is already a process group leader, or the process
			group ID of a process other than the calling process matches the process
			ID of the calling process.

     getsid(2), setpgid(2), tcgetpgrp(3), tcsetpgrp(3)

     The setsid() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
