This function returns immediately, with no return value. Completion of the operation is signaled via the _aio_, and the final result may be obtained via -<<nng_aio_result.3#,`nng_aio_result()`>>. +`<<nng_aio_result.3#,nng_aio_result()>>`. That result will either be zero or an error code. The I/O operation completes as soon as at least one byte has been read, or an error has occurred. Therefore, the number of bytes read may be less than requested. The actual number of bytes read can be determined with -<<nng_aio_count.3#,`nng_aio_count()`>>. +`<<nng_aio_count.3#,nng_aio_count()>>`. TIP: This function is intended to facilitate uses cases that involve changing the protocol from HTTP, such as WebSocket. |
