Integrating NDPSAddr: Best Practices for Developers

NDPSAddr API Reference: Syntax, Parameters, and Usage Guide The NDPSAddr API is a specialized programming interface used to manage, resolve, and manipulate Network Directory Printing Services (NDPS) addressing structures. It allows developers to programmatically interface with network printing architectures, ensuring accurate routing of print jobs across enterprise directories. 1. Overview and Core Function

The NDPSAddr API translates complex network directory paths into actionable hardware addresses. It acts as a bridge between the logical directory service and the physical network printing layer. Developers use this API to: Validate printer network addresses. Convert directory paths to physical addresses. Query printer status using address attributes. 2. API Syntax

The core function follows a standard C-style procedural syntax execution.

STATUS NDPSAddrResolve( NDPSContextHandle context, const charpszDirectoryPath, DWORD dwFlags, PNDPS_ADDR_INFO pAddrInfo ); Use code with caution. 3. Parameter Reference

The function requires four primary arguments to execute successfully:

context (Input): A valid handle to the NDPS environment session.

pszDirectoryPath (Input): Null-terminated string containing the logical printer path.

dwFlags (Input): Bitmask values controlling resolution behavior (e.g., cache bypass).

pAddrInfo (Output): Pointer to a structure that receives the resolved address details. Flag Bitmask Options Flag Constant Description NDPS_FL_FORCE_RETRY 0x00000001 Bypasses local address cache. NDPS_FL_FORWARD_LOOKUP 0x00000002 Restricts resolution to IPv4/IPv6 endpoints. 4. Usage Guide and Code Example

The following scenario demonstrates how to initialize the address structure, call the API, and handle potential errors.

#include #include #include void ResolvePrinter() { NDPSContextHandle context = GetCurrentNDPSContext(); NDPS_ADDR_INFO addrInfo = {0}; STATUS status; // Execute the address resolution status = NDPSAddrResolve( context, “NDPS://Tree/Context/Marketing-LJ4”, NDPS_FL_FORWARD_LOOKUP, &addrInfo ); // Error handling and verification if (status == SUCCESS) { printf(“Resolution successful. “); printf(“Physical Port: %d “, addrInfo.dwPort); } else { printf(“Error encountered: Code 0x%08X “, status); } } Use code with caution. 5. Return Values

The API returns a STATUS type represented by an unsigned 32-bit integer:

0x00000000 (SUCCESS): The address was successfully resolved.

0x8004010F (ERR_NOT_FOUND): The specified printer directory path could not be located.

0x80070005 (ERR_ACCESS_DENIED): The calling context lacks permission to read the address.
