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