WSA_QOS_NO_RECEIVERS - 11008 (0x2B00)

Technical Meaning

The WSA_QOS_NO_RECEIVERS error code, with the numeric value 11008 and hexadecimal representation 0x2B00, is returned by Windows API functions when a quality of service (QoS) request cannot be fulfilled because there are no receivers available to process it. This typically occurs in network programming scenarios where QoS policies or configurations are being applied.

Error Details

This error code indicates that the system attempted to establish a connection or configure a network resource with specific quality of service requirements, but found that no entities within the network infrastructure were capable of handling these requirements. The absence of receivers could be due to various factors such as misconfiguration, insufficient resources, or limitations in the network setup.

Usage Context

The WSA_QOS_NO_RECEIVERS error is commonly encountered in scenarios where developers are implementing QoS policies for network communications. This might include setting up priority levels, bandwidth allocations, or other quality of service parameters that require specific network entities to be present and capable of handling the request.

Developer Interpretation

When this error code is returned, it signifies that the application should check its configuration and ensure that all necessary components are correctly set up. The developer must verify that the QoS settings are appropriate for the current network environment and that there are no misconfigurations or limitations preventing the establishment of a connection with the required quality.

Related Errors

• WSAEADDRNOTAVAIL (10049): Address not available in address family. This error might occur if the requested QoS settings cannot be mapped to an available network resource.
• WSAECONNREFUSED (10061): Connection refused. This could indicate that a receiver is present but has explicitly rejected the connection attempt, possibly due to policy or configuration issues.

FAQ

What does WSA_QOS_NO_RECEIVERS mean?

It means there are no receivers available to process the quality of service request.

How can I resolve this issue?

Review your network configuration and ensure that all necessary components are correctly set up to handle QoS requests. Verify that the requested settings are compatible with the current network environment.

Summary

The WSA_QOS_NO_RECEIVERS error code is a generic indication that a quality of service request could not be fulfilled due to the absence of suitable receivers in the network infrastructure. Developers should carefully review their configurations and ensure that all necessary components are correctly set up to handle such requests.
