Close an open file

closefile(handle)

Closes the file descriptor handle.

Software function for closing a file by its descriptor can be implemented using the following code: closefile(file_descriptor) This example uses the `closefile' function, which closes the file by its descriptor. If the file is successfully closed, the function closes the file successfully.

The function is used after writing data sequentially written to a file and then closes the file using the file closure function. This ensures that all data changes have been written to the file and all resources associated with the file have been released.
