Text Buffer Utilities

NAME

 CopyTextBufferBlock

SYNOPSIS

#include <textbuff.h>
  ...
extern int CopyTextBufferBlock(text, buffer, start_position, end_position)
TextBuffer ∗ text;
char ∗ buffer;
TextPosition start_position;
TextPosition end_position;

DESCRIPTION

The CopyTextBufferBlock function is used to retrieve a text block from the text TextBuffer.  The block is defined as the characters between start_position and end_position inclusive.  It returns the number of bytes copied; if the parameters are invalid the return value is zero (0). 

SEE ALSO

GetTextBufferLocation(3), GetTextBufferChar(3), GetTextBufferLine(3)

NOTE

The storage for the copy is allocated by the caller.  It is the responsibility of the caller to ensure that enough storage is allocated to copy end_position - start_position + 1 bytes.
