buffer_feed - Man Page

#include <buffer.h>

int buffer_feed(buffer* b);

If the string is nonempty, buffer_feed returns the length of the string. If the string is empty, buffer_feed uses the read operation to feed data into the string; it then returns the new length of the string, or 0 for end of input, or -1 for error.
