## -description


Gets the package family name for the specified process.


## -parameters




### -param hProcess [in]

Type: <b>HANDLE</b>

A handle to the process that has the <b>PROCESS_QUERY_INFORMATION</b> or <b>PROCESS_QUERY_LIMITED_INFORMATION</b> access right. For more information, see <a href="https://docs.microsoft.com/windows/desktop/ProcThread/process-security-and-access-rights">Process Security and Access Rights</a>.


### -param packageFamilyNameLength [in, out]

Type: <b>UINT32*</b>

On input, the size of the <i>packageFamilyName</i> buffer, in characters. On output, the size of the package family name returned, in characters, including the null-terminator.


### -param packageFamilyName [out, optional]

Type: <b>PWSTR</b>

The package family name.


## -returns



Type: <b>LONG</b>

</dl>
</td>
<td width="60%">
The process has no package identity.

</td>
</tr>
<tr>
<td width="40%">
<dl>
<dt><b>ERROR_INSUFFICIENT_BUFFER</b></dt>
</dl>
</td>
<td width="60%">
The buffer is not large enough to hold the data. The required size is specified  by <i>packageFamilyNameLength</i>.
