Moving Text Between Buffers

xfer(char *buf, int from, int to)

buf_xfer(int bnum, int from, int to) /* buffer.e */

raw_xfer(int bnum, int from, int to)

buf_xfer_colors(int bnum, int from, int to)

grab_buffer(int bnum)       /* buffer.e */

The xfer( ) subroutine transfers characters from one buffer to another. It copies the characters between from and to in the current buffer and inserts them at point in the named buffer. It positions the mark in the named buffer just before the inserted characters, and positions its point right after the insertion. The current buffer doesn't change. The buf_xfer( ) subroutine works similarly, but accepts a buffer number instead of a name. Both use the raw_xfer( ) primitive to transfer the text.

The buf_xfer_colors( ) subroutine is like buf_xfer( ), but copies any colors set by set_character_color( ) as well. Often it's used following a call to the recolor_buffer_range( ) subroutine, which applies the current mode's coloring rules to a range of the buffer, but it can be used alone if the buffer's coloring was set in a different way.

The grab_buffer( ) subroutine copies text in the other direction. It inserts the text of buffer number bnum into the current buffer before point, setting the mark before the inserted text.
