+FUNCTION
+<<tmpfile>>---create a temporary file
+
+INDEX
+	tmpfile
+INDEX
+	_tmpfile_r
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	FILE *tmpfile(void);
+
+	FILE *_tmpfile_r(struct _reent *<[reent]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	FILE *tmpfile();
+
+	FILE *_tmpfile_r(<[reent]>)
+	struct _reent *<[reent]>;
+
+DESCRIPTION
+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>>.
