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()
