"Q119591 How to Obtain Microsoft Support Files from Online Services" Microsoft used the most current virus detection software available on the date of posting to scan this file for viruses. Once posted, the file is housed on secure servers that prevent any unauthorized changes to the file.

Windows contains its own set of file I/O functions to perform the basic operations such as file open, close, read, write, and so forth; however, there is no function to copy a file. The COPY.C module included in this sample can be plugged into any application or dynamic-link library (DLL). Some of the features of this module are:


 * The ability to rename the output file
 * The ability to copy the file date/time stamp and attributes
 * Nondependency upon the C run time due to the use of inline assembly
 * Robust error reporting

For information on how to call the CopyFile function, please refer to the comment block inside of COPY.C.
