Module Name:

    uuidfmt.c {v1.00}

Abstract:

This module contains I_UuidStringGenerate, which coalesces
the procedures UuidCreate and UuidToString to create a UUID
in one of the formats IDL, C struct, or plain.

/*

Routine Description:

    This routine creates a UUID in one of several string representations.

Arguments:

    Flag - UUIDGEN_FORMAT_IDL gives an IDL template;
           UUIDGEN_FORMAT_CSTRUCT gives a C Struct;
           UUIDGEN_FORMAT_PLAIN gives a plain UUID.

    UuidFormattedString - Must be preinitialized; will contain result.

    InterfaceName - Name of desired interface; used for IDL and C Structs.

Return Value:

    RPC_S_OK - We successfully converted the UUID into its string
        representation.

    RPC_S_OUT_OF_MEMORY - Insufficient memory is available to allocate
        a string.

    RPC_S_UUID_NO_ADDRESS - We were unable to obtain the ethernet or
        token ring address for this machine.
