NAME
tcgetpgrp - get foreground process group ID SYNOPSIS
#include <sys/types.h> #include <unistd.h> pid_t tcgetpgrp(int fildes); DESCRIPTION
The tcgetpgrp() function will return the value of the process group ID of the foreground process group associated with the terminal. If there is no foreground process group, tcgetpgrp() returns a value greater than 1 that does not match the process group ID of any exist- ing process group. The tcgetpgrp() function is allowed from a process that is a member of a background process group; however, the information may be subse- quently changed by a process that is a member of a foreground process group. RETURN VALUES
Upon successful completion, tcgetpgrp() returns the value of the process group ID of the foreground process associated with the terminal. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The tcgetpgrp() function will fail if: EBADF The fildes argument is not a valid file descriptor. ENOTTY The calling process does not have a controlling terminal, or the file is not the controlling terminal. ATTRIBUTES
