setbuf[edit | edit source]
#include <cstdio> void setbuf( FILE *stream, char *buffer );
The setbuf() function sets stream to use buffer, or, if buffer is NULL, turns off buffering. This function expects that the buffer be BUFSIZ characters long - since this function does not support specifying the size of the buffer, buffers larger than BUFSIZ will be partly unused.
