+* NAME
+*        tmpfileplus - create a unique temporary file
+*
+* SYNOPSIS
+*        FILE *tmpfileplus(const char *dir, const char *prefix, char **pathname, int keep)
+*
+* DESCRIPTION
+*        The tmpfileplus() function opens a unique temporary file in binary
+*        read/write (w+b) mode. The file is opened with the O_EXCL flag,
+*        guaranteeing that the caller is the only user. The filename will consist
+*        of the string given by `prefix` followed by 10 random characters. If
+*        `prefix` is NULL, then the string "tmp." will be used instead. The file
+*        will be created in an appropriate directory chosen by the first
+*        successful attempt in the following sequence:
+*
+*        a) The directory given by the `dir` argument (so the caller can specify
+*        a secure directory to take precedence).
+*
+*        b) The directory name in the environment variables:
+*
+*          (i)   "TMP" [Windows only]
+*          (ii)  "TEMP" [Windows only]
+*          (iii) "TMPDIR" [Unix only]
+*
+*        c) `P_tmpdir` as defined in <stdio.h> [Unix only] (in Windows, this is
+*        usually "\", which is no good).
+*
+*        d) The current working directory.
+*
+*        If a file cannot be created in any of the above directories, then the
+*        function fails and NULL is returned.
+*
+*        If the argument `pathname` is not a null pointer, then it will point to
+*        the full pathname of the file. The pathname is allocated using `malloc`
+*        and therefore should be freed by `free`.
+*
+*        If `keep` is nonzero and `pathname` is not a null pointer, then the file
+*        will be kept after it is closed. Otherwise the file will be
+*        automatically deleted when it is closed or the program terminates.
+*
+*
+* RETURN VALUE
+*        The tmpfileplus() function returns a pointer to the open file stream,
+*        or NULL if a unique file cannot be opened.
+*
+*
+* ERRORS
+*        ENOMEM Not enough memory to allocate filename.

+*
+* DESCRIPTION
+*        Same as tmpfileplus() except receives filename in a fixed-length buffer. No allocated memory to free.

+* ERRORS
+*        E2BIG Resulting filename is too big for the buffer `pathnamebuf`.
