Text Buffer Utilities

NAME

 RegisterTextBufferUpdate

SYNOPSIS

#include<textbuff.h>
  ...
extern void RegisterTextBufferUpdate(text, f, d)
TextBuffer ∗ text;
TextUpdateFunction f;
caddr_t d;

DESCRIPTION

The RegisterTextBufferUpdate procedure associates the TextUpdateFunction f and data pointer d with the given TextBuffer text.  This update function will be called whenever an update operation is performed on the TextBuffer.  See ReplaceBlockInTextBuffer for more details. 

SEE ALSO

UnregisterTextBufferUpdate(3), ReadStringIntoTextBuffer(3),
ReadFileIntoTextBuffer(3)

NOTE

Calling this function increments a reference count mechanism used to determine when to actually free the TextBuffer.  Calling the function with a NULL value for the function circumvents this mechanism.
