WebApr 5, 2012 · Hi all, I'm working with Visual Studio 2010 C++. In my program I'm trying to read a bin file with a random size. I've tried the fread function as follows: char *Pointer = new char [1600]; Size = sizeof (0xA0); inputPointer = fread (Pointer, Size, 1600, FILE *fin); But it seems that the inputPointer size equals to 0x115 instead of ~1200 bytes.

I understand about the "don't cast malloc" holy war frustration, but the bottom line is a char is not guaranteed to be 8 bits wide. Even beyond that though, replacing the sizeof with a const is not a great idea for code maintainability purposes; if anything, I would suggest in this case to use sizeof(*data) so that if datas type changes in the future, the size intention is still met. kst thermostatWebJan 28, 2015 · sizeof(char) is guaranteed to be 1. If you think that in future you might want to use another representation of characters (say, wchar_t), you'd have to modify code in more than one place. It is much safer to infer size from the variable, rather than from type: *line = calloc(..., sizeof(**line)); This way there is a single modification point. kst time to philippine timeWebJul 27, 2024 · The fread () function is the complementary of fwrite () function. fread () function is commonly used to read binary data.
