sl@0: * FUNCTION
sl@0: * <<tmpfile>>---create a temporary file
sl@0: * INDEX
sl@0: * tmpfile
sl@0: * INDEX
sl@0: * _tmpfile_r
sl@0: * ANSI_SYNOPSIS
sl@0: * #include <stdio.h>
sl@0: * FILE *tmpfile(void);
sl@0: * FILE *_tmpfile_r(void *<[reent]>);
sl@0: * TRAD_SYNOPSIS
sl@0: * #include <stdio.h>
sl@0: * FILE *tmpfile();
sl@0: * FILE *_tmpfile_r(<[reent]>)
sl@0: * char *<[reent]>;
sl@0: * Create a temporary file (a file which will be deleted automatically),
sl@0: * using a name generated by <<tmpnam>>.  The temporary file is opened with
sl@0: * the mode <<"wb+">>, permitting you to read and write anywhere in it
sl@0: * as a binary file (without any data transformations the host system may
sl@0: * perform for text files).
sl@0: * The alternate function <<_tmpfile_r>> is a reentrant version.  The
sl@0: * argument <[reent]> is a pointer to a reentrancy structure.
sl@0: * RETURNS
sl@0: * <<tmpfile>> normally returns a pointer to the temporary file.  If no
sl@0: * temporary file could be created, the result is NULL, and <<errno>>
sl@0: * records the reason for failure.
sl@0: * PORTABILITY
sl@0: * Both ANSI C and the System V Interface Definition (Issue 2) require
sl@0: * <<tmpfile>>.
sl@0: * Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
sl@0: * <<isatty>>, <<lseek>>, <<open>>, <<read>>, <<sbrk>>, <<write>>.
sl@0: * <<tmpfile>> also requires the global pointer <<environ>>.
