FSfread Function

size_t FSfread(
    void * ptr, 
    size_t size, 
    size_t n, 
    FSFILE * stream
);

The FSfread function will read data from the specified file. First, the appropriate sector of the file is loaded. Then, data is read into the specified buffer until the specified number of bytes have been read. When a cluster boundary is reached, a new cluster will be loaded. The parameters 'size' and 'n' indicate how much data to read. 'Size' refers to the size of one object to read (in bytes), and 'n' will refer to the number of these objects to read. The value returned will be equal to 'n' unless an error occured or the user tried to read beyond the end of the file.

File is opened in a read mode

size_t - number of units read
