NAME

       setpgrp - set process group ID

SYNOPSIS

       #include <sys/types.h>
       #include <unistd.h>

       pid_t setpgrp(void);

DESCRIPTION

       If  the calling process is not already a session leader, the setpgrp() function makes it one by setting its process group ID and session ID
       to the value of its process ID, and releases its controlling terminal. See Intro(2) for more information on process group IDs  and  session
       leaders.

RETURN VALUES

       The setpgrp() function returns the value of the new process group ID.

ERRORS

       No errors are defined.

NAME

       setpgrp - set the process group ID

SYNOPSIS

       #include <unistd.h>

       pid_t setpgrp(void);

DESCRIPTION

       If the calling process is not already a session leader, setpgrp() sets the process group ID of the calling process to the process ID of the
       calling process. If setpgrp() creates a new session, then the new session has no controlling terminal.

       The setpgrp() function has no effect when the calling process is a session leader.

RETURN VALUE

       Upon completion, setpgrp() shall return the process group ID.

ERRORS

       No errors are defined.
