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>>.
