Function accept_direct [src]

Queues an accept using direct (registered) file descriptors. To use an accept direct variant, the application must first have registered a file table (with register_files). An unused table index will be dynamically chosen and returned in the CQE res field. After creation, they can be used by setting IOSQE_FIXED_FILE in the SQE flags member, and setting the SQE fd field to the direct descriptor value rather than the regular file descriptor. Available since 5.19
