* Description:

* FUNCTION

* <<tmpfile>>---create a temporary file

* INDEX

* tmpfile

* INDEX

* _tmpfile_r

* ANSI_SYNOPSIS

* #include <stdio.h>

* FILE *tmpfile(void);

* FILE *_tmpfile_r(void *<[reent]>);

* TRAD_SYNOPSIS

* #include <stdio.h>

* FILE *tmpfile();

* FILE *_tmpfile_r(<[reent]>)

* char *<[reent]>;

* Create a temporary file (a file which will be deleted automatically),

* using a name generated by <<tmpnam>>.  The temporary file is opened with

* the mode <<"wb+">>, permitting you to read and write anywhere in it

* as a binary file (without any data transformations the host system may

* perform for text files).

* The alternate function <<_tmpfile_r>> is a reentrant version.  The

* argument <[reent]> is a pointer to a reentrancy structure.

* RETURNS

* <<tmpfile>> normally returns a pointer to the temporary file.  If no

* temporary file could be created, the result is NULL, and <<errno>>

* records the reason for failure.

* PORTABILITY

* Both ANSI C and the System V Interface Definition (Issue 2) require

* <<tmpfile>>.

* Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,

* <<isatty>>, <<lseek>>, <<open>>, <<read>>, <<sbrk>>, <<write>>.

* <<tmpfile>> also requires the global pointer <<environ>>.

*
