getpt − open the pseudo-terminal master (PTM)
#include <stdlib.h>
int getpt(void)
getpt() opens a pseudo-terminal master and returns its file descriptor. It is equivalent to open("/dev/ptmx",O_RDWR|O_NOCTTY) on Linux systems, though the pseudo-terminal master is located elsewhere on some systems that use GNU Libc.
getpt() returns an open file descriptor upon successful completion. Otherwise, it returns −1 and sets errno to indicate the error.
getpt() is specific to GNU Libc.
