Pascal String Builder
|
|||
|
|
=====================
|
|||
|
|
|
|||
|
|
These functions operate on the Pascal-style Str255 string type, which consists
|
|||
|
|
of a length byte, followed by 0-255 characters of text. Pascal string literals
|
|||
|
|
can be written by putting \p at the beginning of the literal (this is a C
|
|||
|
|
extension), and have an unsigned char type. C-style strings (null-terminated,
|
|||
|
|
char type) are not used.
|
|||
|
|
|
|||
|
|
The functions here construct strings for human consumption only, not
|
|||
|
|
machine-readable strings. Strings which overflow the destination buffer are
|
|||
|
|
silently truncated, with an ellipsis added to the end of the buffer to show that
|
|||
|
|
it’s been truncated.
