Bytes

[Shell]

Hello everyone!

I got a question, hope someone knows a answer
Im using fopen and fgetc to read bytes from a file. How do i read a integer from a file this way? I want to read a header of a file.

Thanks in advance,

Just read 4 bytes, and there's your int (32-bit, of course...)

Ah, so its possible. Can you give me an example on how to do this? How to stuff those bytes into one integer i mean, i now.. i'm a newbie

int i;
fread(&i, sizeof(int), 1, fp);

...I think, been a while since I did C

fread(target, size, count, file), where size is the size of each element, and count is how many you're reading. In this case, you're reading 1 4-byte number.



I assume it's a binary file, right...

Thanks! That works!
