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

     setsid — create session and set process group ID

     #include <sys/types.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 group.

     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

     setpgid(3), tcgetpgrp(3), tcsetpgrp(3)

     The setsid function is expected to be compliant with the IEEE Std
     1003.1-1988 (“POSIX.1”) specification.
