PackageNameAndPublisherIdFromFamilyName function

-description

Gets the package name and publisher identifier (ID) for the specified package family name.

-parameters

-param packageFamilyName [in]

Type: PCWSTR

The family name of a package.

-param packageNameLength [in, out]

Type: UINT32*

On input, the size of the packageName buffer, in characters. On output, the size of the package name returned, in characters, including the null-terminator.

-param packageName [out, optional]

Type: PWSTR

The package name.

-param packagePublisherIdLength [in, out]

Type: UINT32*

On input, the size of the packagePublishId buffer, in characters. On output, the size of the publisher ID returned, in characters, including the null-terminator.

-param packagePublisherId [out, optional]

Type: PWSTR

The package publisher ID.

-returns

Type: LONG

If the function succeeds it returns ERROR_SUCCESS. Otherwise, the function returns an error code. The possible error codes include the following.

Return code	Description
ERROR_INSUFFICIENT_BUFFER	One of the buffers is not large enough to hold the data. The required sizes are specified by packageNameLength and packagePublisherIdLength.

-remarks

For info about string size limits, see Identity constants.
