NAME¶

knet_handle_new - create a new instance of a knet handle

SYNOPSIS¶

#include <libknet.h>

knet_handle_t knet_handle_new(


    knet_node_id_t host_id,


    int            log_fd,


    uint8_t        default_log_level
);

DESCRIPTION¶

knet_handle_new

host_id - Each host in a knet is identified with a unique ID. when creating a new handle local host_id must be specified (0 to UINT16T_MAX are all valid). It is the user's responsibility to check that the value is unique, or bad things might happen.

log_fd - Write file descriptor. If set to a value > 0, it will be used to write log packets from libknet to the application. Setting to 0 will disable logging from libknet. It is possible to enable logging at any given time (see logging API). Make sure to either read from this filedescriptor properly and/or mark it O_NONBLOCK, otherwise if the fd becomes full, libknet could block.

default_log_level - If logfd is specified, it will initialize all subsystems to log at default_log_level value. (see logging API)

RETURN VALUE¶

on success, a new knet_handle_t is returned. on failure, NULL is returned and errno is set.
