It returns non-zero value if successful otherwise, zero. Here is the syntax of feof () in C language, The lseek () function allows the file offset to be set beyond the end of the file (but this does not change the size of the file). If data is later written at this point, subsequent reads of the data in the gap (a "hole") return null bytes (’\0’) until data is actually written into the gap. and perhaps a small oversite lseek () does not take a filename as it's first parameter. Rather it requires a 'file descriptor', which can be obtained (from a filename) by implementing 'open ()': int fd = open (filename, O_RDONLY); Now, fd can be passed to 'lseek ()', instead of the filename. Repeat the above steps till the end of the file. Initialise the array of length of the given message in the given file.

If data is later written at this point, subsequent reads of the data in the gap (a "hole") return null bytes ('\0') until data is actually written into the gap. The lseek() function allows the file offset to be set beyond the end of existing data in the file.
