The problem is, for some reason fopen returns NULL, and because of that, my program is crashing at the fwrite statement. ...
I'm trying to use fwrite to write an array of 65,536 8-bit values with a few other pieces of data added in. While I know how to use fwrite, the problem I'm having is with fopen - the pointer is always 0 when using wb mode. Basically: Code: int StartHeight; char SlopeData[65536]; ... // in a function GetCurrentDirectory(MAX_PATH, BasePath); // the ...
Ok, I'm trying to write a file out, but the data needs to be in big endian format. Intel of course is in little endian. I search around for stuff, and with the standard C library, it seems nothing is around to output easiliy from one to the other, or to even specify which endianess you are using. This seems like ...
Hi All, I have a clarification. As we know we can use open, read, write (low level functions) for file IO. Similarly fopen,fread,fwrite (high level functions). But when to use which functions?
