        int setvbuf( FILE *stream, char *buf, int type, size_t size )

       - prototype in stdio.h

       - causes buf to be used for I/O buffering instead of the auto-
         matically allocated buffer; used after given stream is opened
         and before output
       - in setvbuf, if buf is NULL, a buffer is allocated via malloc()
       - no I/O to the file should occur until after buffering is set

       - see   setbuf()
