getpt — open the pseudo-terminal master (PTM)
#define _GNU_SOURCE #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.
