fclose()
You can use the fclose()method to close a file.
SYNTAX
int fclose (FILE * stream);
The stream parameter specifies a pointer to a FILE object that specifies the file stream to be
closed.
If the file has been closed successfully, this method returns a zero value. Otherwise, it returns
EOF
(End-of-File).
EXAMPLE

FILE * pFile;
fclose (pFile)
