freadis a C standard library function, not a C++ function. It is used for reading binary data from a file in C. Syntax: size_tfread(void*ptr,size_t size,size_t count,FILE*stream); ptr: Pointer to the block of memory where data will be read into. ...
The underlying type of the objects pointed to by both the source and destination pointers are irrelevant for this function; The result is a binary copy of the data. The function does not check for any terminating null character in source - it always copies exactly num bytes. ...
