The windows need not be the same size. Those characters - in the source window that intersect with the destination window - are copied, so that the characters appear in the same physical - position on the screen. The difference between the two functions - is that overlay() is non-destructive (blanks are not copied) - while overwrite() is destructive (blanks are copied). - - copywin() is similar, but doesn't require that the two windows - overlap. The arguments src_tc and src_tr specify the top left - corner of the region to be copied. dst_tc, dst_tr, dst_br, and - dst_bc specify the region within the destination window to copy - to. The argument "overlay", if TRUE, indicates that the copy is - done non-destructively (as in overlay()); blanks in the source - window are not copied to the destination window. When overlay is - FALSE, blanks are copied. - - Return Value: - All functions return OK on success and ERR on error. - - Portability X/Open BSD SYS V - overlay Y Y Y - overwrite Y Y Y - copywin Y - 3.0 - -**man-end****************************************************************/ - -/* Thanks to Andreas Otte <venn@@uni-paderborn.de> for the - corrected overlay()/overwrite() behavior. */ - -static int _copy_win(const WINDOW *src_w, WINDOW *dst_w, int src_tr, - int src_tc, int src_br, int src_bc, int dst_tr, - int dst_tc, bool _overlay) -{ - int col, line, y1, fc, *minchng, *maxchng;
