Hi,

I started a binding to libpng so I can load some images into OpenGL, but 
the library uses setjmp and longjmp for error handling.  This is very 
new to me but from what I understand it's some form of library "goto" 
which allows code to jump to predefined points on given events.  When 
dealing with such things is it best to wrap around the code with C and 
catch all these longjmps with setjmps, returning error flags if 
something fails?


Thanks,
Chris
