TCGETPGRP(3)               BSD Programmer's Manual                TCGETPGRP(3)


     tcgetpgrp - get foreground process group ID


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

     tcgetpgrp(int fd);


     The tcgetpgrp() function returns the value of the process group ID of the
     foreground process group associated with the terminal device. If there is
     no foreground process group, tcgetpgrp() returns an invalid process ID.


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

     [EBADF]       The fd argument is not a valid file descriptor.

     [ENOTTY]      The calling process does not have a controlling terminal or
                   the underlying terminal device represented by fd is not the
                   controlling terminal.


     setpgid(2), setsid(2), tcsetpgrp(3)


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