TipcMsgUpdateNamedUnknown

TipcMsgUpdateNamedUnknown — update a field with an unknown or non-existent value in a message with new data

T_BOOL TipcMsgUpdateNamedUnknown(msg, name, type) 
T_IPC_MSG msg; 
T_STR name; 
T_IPC_FT type;

msg — message to append field to

name — name of the field

type — type of the field (such as T_IPC_FT_INT2, T_IPC_FT_INT4)

TRUE if the append was successful, FALSE otherwise.

If TipcMsgUpdateNamedUnknown fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_NULL_PTR — msg, name or value is null

T_ERR_MSG_INVALID — msg was not a valid message

T_ERR_FT_MISMATCH — the message type grammar did not match the fields in the message

T_ERR_READ_ONLY — the message was marked read-only. This happens if the message is a field in another message.

T_ERR_VALUE_INVALID — value was not a valid value

TipcMsgUpdateNamedUnknown updates a named field with an unknown or non-existent value.

This example changes the value of the named field "data":

T_STR data; 
if (!TipcMsgUpdateNamedUnknown(msg, "data", data)) { 
  return;  /* error */ 
}
