# tibrvMsg_Create()

Function

## Declaration

    tibrv_status tibrvMsg_Create(
        tibrvMsg*    message);
    tibrv_status tibrvMsg_CreateEx(
        tibrvMsg*    message,
        tibrv_u32    initialStorage);

## Purpose

Allocate storage and initialize it as a new message.

## Remarks

This function allocates storage for the new message. A program owns the messages that it creates, and must destroy them to reclaim the storage. That is, each call to this function must be paired with a call to tibrvMsg_Destroy().

Programs can add address information to the message using tibrvMsg_SetSendSubject(), and tibrvMsg_SetReplySubject().

## Message Size

When adding data to a message would overflow the allocated space, the message automatically expands by allocating additional storage. However, when creating messages that contain many small fields, you can optimize program performance by pre-allocating sufficient storage initially.

Parameter | Description
`message` | The function stores a pointer to the new message in this location.
`initialStorage` | Initial space (in bytes) to allocate for the message.
