[mapserver-users] ms_error question

[Giorgio Volpe]

Some time passed ...
I've studied the matter a bit!

The error is generated when msSHPWhichShapes tries to look for an index
(.qix file) to retrieve shapes for layers ... I've no qix file so it is
right ... but it should be a "warning", On the contrary, when I call 

	$img=$map->draw()

then I found $mapscript::ms_error->{code} = 1 (Unable to access file)
so i cannot use it to understand if draw() was ok.

I didn't found written anywhere that we have to look ms_error after
calling draw method ... is it correct?
I tried to assume that all is ok if $img is defined but in some cases
that was wrong because also if $img was defined than system crashed when
i tried to save the img.
