FUNCTION
<<tmpfile64>>---create a large temporary file
INDEX
tmpfile64
INDEX
_tmpfile64_r
ANSI_SYNOPSIS
#include <stdio.h>
FILE *tmpfile64(void);
FILE *_tmpfile64_r(void *<[reent]>);
TRAD_SYNOPSIS
#include <stdio.h>
FILE *tmpfile64();
FILE *_tmpfile64_r(<[reent]>)
char *<[reent]>;
DESCRIPTION
Create a large 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 file may be larger than 2GB.
The alternate function <<_tmpfile64_r>> is a reentrant version. The
argument <[reent]> is a pointer to a reentrancy structure.
Both <<tmpfile64>> and <<_tmpfile64_r>> are only defined if __LARGE64_FILES
is defined.
RETURNS
<<tmpfile64>> 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
<<tmpfile64>> is a glibc extension.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
<<isatty>>, <<lseek64>>, <<open64>>, <<read>>, <<sbrk>>, <<write>>.
<<tmpfile64>> also requires the global pointer <<environ>>.
