How do I get the size of a file in C?
Using stat() function The stat() function takes the file path and returns a structure containing information about the file pointed by it. To get the size of the file in bytes, use the st_size field of the returned structure.
What is Off_t in C?
off_t is normally defined as a signed, 32-bit integer. In the programming environment which enables large files, off_t is defined to be a signed, 64-bit integer. 64-bit file offset, measured in bytes from the beginning of a file or device.

How big is a Size_t in C++?
size_t type is a base unsigned integer type of C/C++ language. It is the type of the result returned by sizeof operator. The type’s size is chosen so that it can store the maximum size of a theoretically possible array of any type. On a 32-bit system size_t will take 32 bits, on a 64-bit one 64 bits.
How many bytes is Off_t?
int , long , ptr , and off_t are all 32 bits (4 bytes) in size. int is 32 bits in size. long , ptr , and off_t are all 64 bits (8 bytes) in size.

How to get the file size of a file?
You can use GetFileSize or GetFileSizeEx. If you have the file descriptor fstat () returns a stat structure which contain the file size. It’s kind of silly that the standard C library doesn’t have such a function, but I can see why it’d be difficult as not every “file” has a size (for instance /dev/null)
How do I add a Fileno to a stream?
Add “fd = fileno(f);” if you have a stream (e.g. from fopen), not a file descriptor. Needs error checking. – ysth
