[out] UINT *pcMappings
);

|
Successfully returned the attribute value. |
|
One of the parameter values is not valid. |

Remarks
The count of alternate ___location mappings returned by GetAlternateLocationMappingCount may be due to not only files in the current component but to files in any of its nonselectable subcomponents.
An alternate ___location mapping is used only during a restore operation and should not be confused with an alternate path, which is used only during a backup operation.
The count returned by GetAlternateLocationMappingCount refers to the number of alternate ___location mappings used in the course of restoring files.
The count is updated by calls to IVssBackupComponents::AddAlternativeLocationMapping.
