File_Length

Returns the length of a file in bytes. Useful when you need to dynamically allocate memory to hold the contents of a file you intend to read. This function was designed to replicated the similarly named filelength function that comes with some distributions of C/C++, particularly on DOS platforms. There doesn't appear to be an equivalent in Unix.

#include <stdio.h>

{
  FILE* stream = fopen("/codecogs/io/binary/file_length.h","rb");
  printf("\n File length=%d", fileLength(stream));
  fclose(stream);

  return 0;
