Reading in a bitmap and getting RGB values

[steve]

I am trying to use ANSI C to read in a bitmap and for each x,y value
get a value for the R, G, and B channels. What would be the best way
to go about this? I had some code working but it would not work for
images larger than 640x480 it would just crash. I have tried using the
Microsoft bmp.c/bmp.h code as well as something called ImageFmtc.c/
ImageFmtc.h and either receive unexpected results or program crashes
on large images.

Thanks for the advise/help on the topic!
