/*
* 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.
*
