#include "sfllbuf.h" char * linebuf_first (LINEBUF *buffer, DESCR *descr)
Fetches the oldest line in the buffer. Returns a pointer that may be used in calls to linebuf next(). Returns NULL if the buffer is empty. The line is stored in the supplied descriptor, and is truncated if the descriptor is too small.
{ ASSERT (buffer); ASSERT (descr); return (linebuf next (buffer, descr, buffer-> tail)); }
