sbpibegt
The application calls the sbpibegt function to get a buffer element to append to an existing buffer.
Syntax
VOID sbpibegt(
PTRBFELT *eltptr
);
Parameters
eltptr
Pointer to a pointer to an element. On return, this points to a pointer to the element obtained, or to NULL if an element was not obtained (an internal error).
Remarks
This function should only be used to get extra elements for an existing buffer. The sepdbubl function should be used to get a new buffer.
The new element should be added to the chain of elements from the existing buffer header and the count of the number of elements updated.
This function is typically used when a received buffer is being reused to transmit a message that is longer than the incoming message.
