    Certification Program The Open Brand certification program
    Test Suite VSU version 4.1.1
    Test Identification CAPIbase/ptsname 3
    Problem Summary TSD4U.00268 This test may fail on implementations that recreate /dev/ptsname if the file does not exist within the filesystem
    Problem Text
    Per the spec for ptsname(), emphasis mine:
    "Upon failure, ptsname() returns 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."

    In this release of our product,
    ptsname() calls stat() which determines that /dev/ttyp0088 does not
    exist. Since this file is always supposed to exist, it creates it on
    the fly, and then ptsname() returns /dev/ttyp0088.


    Test Output
    TEST PURPOSE #3
    A call to char *ptsname(int fildes) when the slave
    device name does not exist in the file system shall
    return NULL.
    PREP: Open master pseudo terminal
    PREP: Get slave pseuc=do terminal
    PREP: Unlock slave device
    PREP: Get name of pseudo terminal device
    PREP: Rename /dev/ttyp0088 to /dev/ttyp0088.save
    TEST: ptsname returns NULL
    ERROR: ptsname returned /dev/ttyp0088
    CLEANUP: Rename /dev/ttyp0088.save to /dev/ttyp0088
    3 FAIL
