posix_openpt() - open a pseudo-terminal master device
SYNOPSIS
Parameters
oflag indicates the file status flags and file access modes of the open file description. Values for oflag are constructed by a bit-

to refer that device. The file status flags and file access modes of the opened file descriptor will be set according to the value of
oflag.
RETURN VALUE
Upon successful completion opens a master pseudo-terminal device and returns a non-negative integer representing the lowest numbered unused
file descriptor. Otherwise, returns -1 and is set to indicate the error.
ERRORS
