tmpfile(3S)


tmpfile, tmpfile64 -- create a temporary file

Synopsis

   #include <stdio.h>
   

FILE *tmpfile (void);

FILE *tmpfile64 (void);

Description

tmpfile creates a temporary file using a name generated by the tmpnam(3S) routine and returns a corresponding FILE pointer. If the file cannot be opened, a NULL pointer is returned. The file is automatically deleted when the process using it terminates or when the file is closed. The file is opened for update (``w+'').

Considerations for large file support

tmpfile64 supports large files, but is otherwise identical to tmpfile. For details on programming for large file capable applications, see ``Large File Support'' on intro(3).
