libnvme_transport_handle_set_submit_exit(9) libnvme API manual NAME libnvme_transport_handle_set_submit_exit - Install a submit-exit callback SYNOPSIS void libnvme_transport_handle_set_submit_exit (struct libnvme_transport_handle *hdl , void (*submit_exit)(struct libnvme_transport_handle *hdl, struct libnvme_passthru_cmd *cmd, int err, void *user_data) ); ARGUMENTS hdl Transport handle to configure submit_exit Callback invoked after a passthrough command completes. The function receives the command, the completion status err (0 for success, a negative errno, or an NVMe status value), and the user_data pointer returned earlier by the submit- entry callback. Implementations typically use this hook for logging, tracing, or freeing per-command state. DESCRIPTION Installs a callback that is invoked when a passthrough command leaves the NVMe submission path. Passing NULL removes any previously installed callback. RETURN None. September 2026 libnvme_transport_handle_set_submit_exit libnvme_transport_handle_set_submit_exit(9)
