# Add Nested Message

Convenience Function

## Declaration

    tibrv_status tibrvMsg_AddMsg(
       tibrvMsg       message,
       const char*    fieldName,
       tibrvMsg       value);
    tibrv_status tibrvMsg_AddMsgEx(
       tibrvMsg       message,
       const char*    fieldName,
       tibrvMsg       value,
       tibrv_u16      fieldId);

## Purpose

Add a field containing a nested submessage.

## Remarks

This function adds only the data portion of the nested message (`value`); it does not include any address information or certified delivery information.

Parameter | Description
`message` | Add the new field to this message.
`fieldName` | Create the new field with this name.
`value` | Add a new field that contains this submessage. The function copies the data into the new field.
`fieldId` | Create the new field with this identifier. Zero is a special value that signifies no field identifier. All non-zero field identifiers must be unique within each message. It is illegal to add a field that has both a `NULL` field name, and a non-zero field identifier.
