QP_ferror()
#include <quintus/quintus.h> int QP_ferror(stream) QP_stream *stream;
Returns non-zero when an error has occurred reading from or writing to the named stream, otherwise zero.
QP_ferror()
is similar to the library function ferror(3V)
,
however the return values differ and stream is a Prolog stream
rather than a stdio
stream.
