NAME
3.48 `tmpfile'--create a temporary file
SYNOPSIS
#include <stdio.h>
FILE *tmpfile(void);
FILE *_tmpfile_r(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'.
