    ptsname

    
    
    

    SYNOPSIS

           #define _XOPEN_SOURCE       /* See feature_test_macros(7) */
           #include <stdlib.h>
    
           char *ptsname(int fd);
    
           #define _GNU_SOURCE         /* See feature_test_macros(7) */
           #include <stdlib.h>
    
           int ptsname_r(int fd, char *buf, size_t buflen);
    
    
    

    DESCRIPTION

           The  ptsname()  function  returns  the name of the slave pseudoterminal
           device corresponding to the master referred to by fd.
    
           The ptsname_r() function is the reentrant equivalent of ptsname().   It
           returns  the  name  of the slave pseudoterminal device as a null-termi-
           nated string in the buffer pointed to  by  buf.   The  buflen  argument
           specifies the number of bytes available in buf.
    
    
    

    RETURN VALUE

           On  success,  ptsname() returns a pointer to a string in static storage
           which will be overwritten by subsequent calls.  This pointer  must  not
           be freed.  On failure, NULL is returned.
    
           On  success,  ptsname_r()  returns  0.   On failure, a nonzero value is
           returned and errno is set to indicate the error.
    
    
    

    ERRORS

           EINVAL (ptsname_r() only) buf is NULL.
    
           ENOTTY fd does not refer to a pseudoterminal master device.
    
           ERANGE (ptsname_r() only) buf is too small.
    
    
    

    VERSIONS

           ptsname() is provided in glibc since version 2.1.
    
    
    

    ATTRIBUTES

       Multithreading (see pthreads(7))
           The ptsname() function is not thread-safe.
    
           The ptsname_r() function is thread-safe.
    
    
    

    CONFORMING TO

           ptsname() is part of the UNIX 98 pseudoterminal support  (see  pts(4)).
           This function is specified in POSIX.1-2001.
    
           ptsname_r()  is a Linux extension.  A version of this function is docu-
           mented on Tru64 and HP-UX, but on those implementations, -1 is returned
           on error, with errno set to indicate the error.  Avoid using this func-
           tion in portable programs.
