PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
ptsname - get name of the slave pseudo-terminal device
SYNOPSIS
#include <stdlib.h> char *ptsname(int fildes);
DESCRIPTION
The ptsname() function shall return the name of the slave pseudo-terminal device associated 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 reentrant is not required to be thread-safe.
RETURN VALUE
Upon successful completion, ptsname() shall return a pointer to a string which is the name of the pseudo-terminal slave device. Upon fail- ure, 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.
ERRORS
No errors are defined. The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
The value returned may point to a static data area that is overwritten by each call to ptsname().
RATIONALE
None.
FUTURE DIRECTIONS
None.
