ptsname - get name of the slave pseudo-terminal device
char *ptsname(int fildes);
The ptsname() function shall return the name of the slave pseudo-terminal device associ-
ated with a master pseudo-terminal device. The fildes argument is a file descriptor that
refers to the master device. The ptsname() function shall return a pointer to a string
containing the pathname of the corresponding slave device.
The ptsname() function need not be reentrant. A function that is not required to be reen-
trant is not required to be thread-safe.
Upon successful completion, ptsname() shall return a pointer to a string which is the name
of the pseudo-terminal slave device. Upon failure, ptsname() shall return a null pointer.
This could occur if fildes is an invalid file descriptor or if the slave device name does
not exist in the file system.
No errors are defined.
