Working with raw data

Working with raw data: C: Data Structures, Pointers, and File Systems

To read and write data to and from a file—as opposed to text—, use the fwrite() and fread() functions. Both the fwrite() and fread() functions have multiple arguments to determine the value written, the size of the value written, the number of data-chunks to write, and the file handle. Multiple data chunks can be written and read at once, such as all elements in an array. The feof() function returns true when the last byte of an open file has been read.
