Initialize IPC functions for datagram and logical link communications and register with the IPC router process. ipc_register must be called prior to using any other communications functions. Following successful execution of this function, an application can start sending and receiving datagram messages or establish logical link communications.
Syntax
int ipc_register (ret_stat, port_index, object_name, maxlnk,
????????????????????????????????????bufsiz)
COR_STATUS *ret_stat;
int *port_index;
char *object_name;
int maxlnk;
int bufsiz;
Input Arguments
object_name
|
The name under which the process registers. The object_name in combination with the node name defines the physical address of the process. All other processes address the process with this name. Maximum length is 10 characters.
|
maxlnk
|
The maximum number of logical links this process can request. Each datagram port and each logical link connection counts as one link.
|
bufsiz
|
The maximum message size used by this process. ipc_dg_alloc may be used to determine this size. The maximum is MAXMSGSIZ, which is defined in netcom.h.
|
Output Arguments
port_index
|
Identifier for port index to be used in datagram functions.
|
ret_stat
|
Pointer to status structure. When the function is not successful, ret_stat.err_code contains one of the following values:
|
|
|
IPC_ERR_BUFTOOBIG
|
103
|
requested buffer too big
|
|
|
IPC_ERR_MAXLNKVIO
|
108
|
max link violation
|
|
|
IPC_ERR_MBXASGN
|
109
|
mailbox assignment failed
|
|
|
IPC_ERR_RTRLNKFAI
|
110
|
router link attempt failed
|
|
|
IPC_ERR_INTERNDAT
|
111
|
internal data failure
|
Return Value
Either COR_SUCCESS, COR_WARNING, or COR_FAILURE. If the function returns anything other than COR_SUCCESS, additional error information can be found in ret_stat.err_msg and ret_stat.err_code.
