tcsetsid -- set session ID associated with a controlling terminal LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/types.h> #include <termios.h> int tcsetsid(int fd, pid_t pid); DESCRIPTION
The tcsetsid() function sets associates a session identified by pid with a controlling terminal specified by fd. This implementation only allows the controlling terminal to be changed by the session leader itself. This implies that pid always has to be equal to the process ID. It is unsupported to associate with a terminal that already has an associated session. Conversely, it is also unsupported to associate to a terminal when the session is already associated with a different terminal. ERRORS
If an error occurs, tcsetsid() 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 file descriptor represented by fd is not a terminal. [EINVAL] The pid argument is not equal to the session ID of the calling process. [EPERM] The calling process is not a session leader. [EPERM] The session already has an associated terminal or the terminal already has an associated session. SEE ALSO
getsid(2), setsid(2), tcgetpgrp(3), tcgetsid(3) HISTORY
A tcsetsid() function first appeared in QNX. It does not comply to any standard. BSD

tcsetpgrp -- set foreground process group ID LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/types.h> #include <unistd.h> int tcsetpgrp(int fd, pid_t pgrp_id); DESCRIPTION
If the process has a controlling terminal, the tcsetpgrp() function sets the foreground process group ID associated with the terminal device to pgrp_id. The terminal device associated with fd 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 pgrp_id must be the same as the process group ID of a process in the same session as the calling process. RETURN VALUES
The tcsetpgrp() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi- cate the error. ERRORS
The tcsetpgrp() function will fail if: [EBADF] The fd argument is not a valid file descriptor. [EINVAL] An invalid value of pgrp_id was specified. [ENOTTY] The calling process does not have a controlling terminal, or the file represented by fd is not the controlling terminal, or the controlling terminal is no longer associated with the session of the calling process. [EPERM] The pgrp_id argument does not match the process group ID of a process in the same session as the calling process. SEE ALSO
setpgid(2), setsid(2), tcgetpgrp(3) STANDARDS
The tcsetpgrp() function is expected to be compliant with the IEEE Std 1003.1-1988 (``POSIX.1'') specification. BSD
