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.
