Syntax

C++


LONG WINAPI GetCurrentPackagePath(
  _Inout_   UINT32 *pathLength,
  _Out_opt_ PWSTR  path
);

Parameters

pathLength [in, out]

Type: UINT32*

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

path [out, optional]

Type: PWSTR

The package path.

Return value

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
APPMODEL_ERROR_NO_PACKAGE	The process has no package identity.
ERROR_INSUFFICIENT_BUFFER	The buffer is not large enough to hold the data. The required size is specified by pathLength.

Examples

C++


#define _UNICODE 1
#define UNICODE 1

#include <Windows.h>
#include <appmodel.h>
#include <malloc.h>
#include <stdio.h>

int __cdecl wmain()
{
    UINT32 length = 0;
    LONG rc = GetCurrentPackagePath(&length, NULL);
    if (rc != ERROR_INSUFFICIENT_BUFFER)
    {
        if (rc == APPMODEL_ERROR_NO_PACKAGE)
            wprintf(L"Process has no package identity\n");
        else
            wprintf(L"Error %d in GetCurrentPackagePath\n", rc);
        return 1;
    }

    PWSTR path = (PWSTR) malloc(length * sizeof(*path));
    if (path == NULL)
    {
        wprintf(L"Error allocating memory\n");
        return 2;
    }

    rc = GetCurrentPackagePath(&length, path);
    if (rc != ERROR_SUCCESS)
    {
        wprintf(L"Error %d retrieving PackagePath\n", rc);
        return 3;
    }
    wprintf(L"%s\n", path);

    free(path);

    return 0;
}
