* FUNCTION
|
|

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

* ANSI_SYNOPSIS
|
|
sl@0
|
22 |
* #include <stdio.h>
|
|
sl@0
|
23 |
* FILE *tmpfile(void);
|
|
sl@0
|
24 |
* FILE *_tmpfile_r(void *<[reent]>);
|
|
sl@0
|
25 |
* TRAD_SYNOPSIS
|
|
sl@0
|
26 |
* #include <stdio.h>
|
|
sl@0
|
27 |
* FILE *tmpfile();
|
|
sl@0
|
28 |
* FILE *_tmpfile_r(<[reent]>)
|
|
sl@0
|
29 |
* char *<[reent]>;
|
|
sl@0
|
30 |
* Create a temporary file (a file which will be deleted automatically),
|
|
sl@0
|
31 |
* using a name generated by <<tmpnam>>. The temporary file is opened with
|
|
sl@0
|
32 |
* the mode <<"wb+">>, permitting you to read and write anywhere in it
|
|
sl@0
|
33 |
* as a binary file (without any data transformations the host system may
|
|
sl@0
|
34 |
* perform for text files).
|
|
sl@0
|
35 |
* The alternate function <<_tmpfile_r>> is a reentrant version. The
|
|
sl@0
|
36 |
* argument <[reent]> is a pointer to a reentrancy structure.
|
|
sl@0
|
37 |
* RETURNS
|
|
sl@0
|
38 |
* <<tmpfile>> normally returns a pointer to the temporary file. If no
|
|
sl@0
|
39 |
* temporary file could be created, the result is NULL, and <<errno>>
|
|
sl@0
|
40 |
* records the reason for failure.
|
|
sl@0
|
41 |
* PORTABILITY
|
|
sl@0
|
42 |
* Both ANSI C and the System V Interface Definition (Issue 2) require
|
|
sl@0
|
43 |
* <<tmpfile>>.
|
|
sl@0
|
44 |
* Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
|
|
sl@0
|
45 |
* <<isatty>>, <<lseek>>, <<open>>, <<read>>, <<sbrk>>, <<write>>.
|
|
sl@0
|
46 |
* <<tmpfile>> also requires the global pointer <<environ>>.
