LINX *linx_open(const char *name, uint32_t options, void *arg);
name is the local part of the huntname to find this LINX endpoint. It
is a null-terminated string, which in Linux may be of any length, but there
may be restrictions due to other implementations, when communicating with
other systems. name does not need to be unique in the system, but if two
LINX endpoints have the same name, it is not specified which one is resolved
when a linx_hunt(3)
call is made that matches the name. From another LINX
endpoints, use linx_hunt() with the huntname, followed by linx_receive()
and linx_sender(), to get the binary identifier (spid) to be used to communicate
with this LINX endpoint. The local LINX binary identifier (spid) for this
endpoint can be fetched with linx_get_spid "()" but is usually not needed
by the owner process.
options and arg are provided to facilitate future extensions and shall
currently be set to 0 resp. NULL.
A LINX endpoint is closed (and its resources are freed) when it is closed
or when the calling process exits.
If the process, owning the LINX endpoint, fork(2) , either the parent or the child __must__ close the LINX handle with linx_close(3) . This is because only one process may use a LINX endpoint and after a fork, both instances will have copies of the LINX handle. In any case the LINX endpoint will not be closed unless closed by both parent and child.
It is possible to retrieve the underlying socket descriptor from a LINX endpoint, with linx_get_descriptor(3) for use if needed, e.g. when an application wants to wait for state changes in multiple sockets.
ENOBUFS or ENOMEM if there is not enough memory.
EPROTONOSUPPORT or EAFNOSUPPORT if linx(7) is not supported by the system.
ENFILE Not enough kernel memory to allocate a new LINX endpoint structure.
EMFILE Process file table overflow.
EACCES Permisson to create a LINX endpoint is denied.
