ptsname(3c)

ptsname(3C)              Standard C Library Functions              ptsname(3C)

NAME
       ptsname - get name of the subsidiary pseudo-terminal device

SYNOPSIS
       #include <stdlib.h>

       char *ptsname(int fildes);

DESCRIPTION
       The ptsname() function returns the name of the subsidiary pseudo-termi‐
       nal  device associated with a manager pseudo-terminal device. fildes is
       a file descriptor returned from a successful open of  the  manager  de‐
       vice.  ptsname() returns a pointer to a string containing the null-ter‐
       minated path name of the subsidiary  device  of  the  form  /dev/pts/N,
       where N is a non-negative integer.

RETURN VALUES
       Upon successful completion, the function ptsname() returns a pointer to
       a  string  which  is the name of the pseudo-terminal subsidiary device.
       This value points to a static data area that  is  overwritten  by  each
       call  to  ptsname().  The returned pointer and the string content might
       also be invalidated if the calling thread is terminated. Upon  failure,
       ptsname()  returns  NULL. This could occur if fildes is an invalid file
       descriptor or if the subsidiary device name does not exist in the  file
       system.
