Programming interface for data communications

A computing system, comprising:

• a memory configured to maintain an application that is executable;
• a processor to execute a programming interface that is configured to:
• receive a request from the application for a kernel to handle data in a request queue, the request queue allocated from a user-mode virtual memory buffer corresponding to the application;
• determine that a kernel-mode execution thread is not assigned to handle the request;
• and
• issue a system call to the kernel for a kernel-mode execution thread to handle the request, the kernel-mode execution thread further configured to handle additional requests from the application without the programming interface having to issue additional system calls to the kernel.

A computing device, comprising:

• at least a memory and a processor to implement a programming interface, the programming interface configured to:
• allocate a request queue and a completion queue from a user-mode virtual memory buffer that corresponds to an application;
• pin the request queue and the completion queue to physical memory;
• map the request queue and the completion queue to kernel-mode system addresses in a kernel to enable the request queue and the completion queue to be accessed by a kernel-mode execution thread;
• receive a request from the application for the kernel to handle data in the request queue;
• issue a system call to the kernel for a kernel-mode execution thread to handle the request, the kernel-mode execution thread further configured to handle additional requests from the application;
• and
• receive the additional requests from the application for the kernel-mode execution thread to handle the data in the request queue, the kernel-mode execution thread configured to handle the additional requests without the programming interface issuing additional system calls.
