i have been cleaning the code of my prog recently and now it seems to be giving me invalid access violations... here''s the problem.. somewhere is defined class mapper { public: char * rom; .... } later i assign a value by mapper->rom = (char *) malloc(0x8000); (inside a function) for (int i=0, i<8000; i++) (this is all symplified) mapper->rom = fgetc(file); when i return from the function i cannot access any of the values... but mapper.rom still equals the same address... essentially i cannot access array values after the function call.. (call by reference).. this should not be.. any help is appreciated... RanXacT

Its late. and i've been coding way to much recently. BUT, I would look at the following line:


for(int i=0;i<8000;i++)
mapper->rom = fgetc(file);


this probably should read

for(int i=0;i<8000;i++)
mapper->rom = (char) fgetc(file);<br></code><br><br>notice the subscript on rom… not sure if that was just a typo on your code though…<br><br>Also, fgetc() returns an integer, so you should cast it before assigning. (no clue why it returns an integer. it just does.)<br>Good luck<br><br>*oof*<br><br>Okay, nevermind that bit about the subscript. You'd think that on a programming related board, programming type code wouldn't be misread as format codes… oh well. <br><br>Edited by - Oofnish on 3/1/00 11:43:16 PM

I knew it must be something stupid... but I am tired.. anyway.. about the subscript, it was a typo.. all of the initialization code was valid... my stupid mistake was that I passed my class to another function by reference in between it''s definition and it''s use. Due to a typo in that function the class was being changed.. so i fixed it and it works now... but Thank you for the help, it was driving me crazy...

As for fgetc i looked up the definition, and sure enough it returns a char in the form of an int.. (which is weird), but then again i am not loosing anything in the truncation... and the compiler isn''t complaining.. (and it works) so hey...

again ThanX for the info,
