Stupid File IO
Ok, this is what I need to do. I need to write a function to open a file, get the data of 1 byte at a certain offset in the file, and store it in a variable. I have been trying to do this for the last two days and I just can't figure it out. This is what I have come up with.
int GetData(char FileName[255])
{
FILE *file;
char buff;
file = fopen(FileName, "r");
fseek(file, 0x3113, 0x0000);
fread(&buff, sizeof(buff), sizeof(buff), file);
}
I suck...
Don't try so hard. Just let it happen.
Maybe you need to open the file in binary mode
Here a small example (didn't test it).
Code:int GetData(char *FileName) { FILE *file; char buff; int offset = 100; file = fopen(FileName, "rb"); if(file == NULL) return -1; if(fseek(file, offset, SEEK_SET) == -1) { fclose(file); return -2; } if(fread(&buff, 1, sizeof(buff), file) != 1) { fclose(fp); return -3; } printf("Your data is: %c\n", buf); fclose(fp); return 0; } }
Thanks, Monster. I got it working now.
You guys are great!
