Name
getpt — open the pseudo-terminal master (PTM)
DESCRIPTION
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.
RETURN VALUE
getpt() returns an open file
descriptor upon successful completion. Otherwise, it returns
−1 and sets errno to
indicate the error.
CONFORMING TO
getpt() is specific to GNU
Libc.
