Comments

The provider calls CoTaskMemAlloc to allocate memory for the array of TRUSTEE structures that represent the members of pMembershipTrustee.

The consumer releases *prgMembers when it no longer needs the TRUSTEE structures. Before freeing this memory, the consumer should free any memory allocated in the pMultipleTrustee or ptstrName elements of each structure. The consumer should call CoTaskMemFree for all these tasks.

If pMembershipTrustee does not contain any members or is not a membership trustee, the provider sets *pcMembers to zero, *prgMembers to NULL, and does not allocate any memory for *prgMembers.
