#include <sys/types.h> #include <unistd.h> int tcsetpgrp(int fildes, pid_t pgid_id);
If the process has a controlling terminal, tcsetpgrp() will set the foreground process group ID associated with the terminal to pgid_id. The file associated with fildes must be the controlling terminal of the calling process and the controlling terminal must be currently associated with the session of the calling process. The value of pgid_id must match a process group ID of a process in the same session as the calling process.
Upon successful completion, 0 is returned. Otherwise, −1 is returned and errno is set to indicate the error.
The tcsetpgrp() function will fail if:
