    Test Identification base/mmap 10
    Problem Summary TSD4U.00065 This test may fail on implementations that do not allow a mmap(PROT_EXEC) call on a file currently open for writing.
    Problem Text
    This test may fail on implementations that do not allow a
    mmap(PROT_EXEC) call on a file currently open for writing.

    This test opens a file with "O_RDWR" flag and then call mmap() to map
    in the file with "PROT_EXEC" flag. Because our implementation does
    not allow mapping a file for execution when the file is currently open
    for writing, the mmap() call fails with errno set to ETXTBSY.
    Test Output
    1 TEST PURPOSE #10
    2 A call to void *mmap(void *addr, size_t len, int prot,
    3 int flags, int fildes, off_t off) shall perform
    4 mapping operations on full pages and shall fill any
    5 partial page at the end of an object with 0 bytes.
    6 PREP: Obtain the system page size by call to
    7 sysconf(_SC_PAGESIZE)
    8 PREP: Establish signal handlers for SIGSEGV
    9 PREP: Allocate memory for buffer
    10 PREP: Open a file and initialize it
    11 ERROR: mmap failed, errno = 26(ETXTBSY - Text file busy)
