CloseFile
int CloseFile (int fileHandle);
Purpose
Closes the file associated with fileHandle. Call OpenFile to obtain a file handle.

Caution The Windows SDK also contains a function with the same name. Include windows.h before including formatio.h to ensure that there are no compilation errors as a result of this naming conflict. Define the SDK_CONFLICT_PRIORITYSDK_CONFLICT_PRIORITY macro to force LabWindows/CVI to use the Windows SDK implementation of this function. |
