restore_old_preprocessor()

void preprocessor_streambuf::restore_old_preprocessor ( )

private

Restores the old preprocessing context.

Appends location and domain directives to the buffer, so that the parser notices these changes.

Referenced by underflow().

underflow()

int preprocessor_streambuf::underflow ( )

overrideprivatevirtual

Inherited from basic_streambuf.

Called by an STL stream whenever it has reached the end of out_buffer_.

Fills buffer_ by calling the current preprocessor, then copies its content into out_buffer_.

Returns

the first character of out_buffer_ if any, EOF otherwise.
