* renamed several helpers so that their name is the same as their
"public alias", which should facilitate the conversion of processor
specific code in the code generator to processor independent code
* some small fixes to the val_ansistring and val_widestring helpers
(always immediately exit if the source string is longer than 255
chars)
* fixed fpc_dynarray_high and fpc_dynarray_length if the dynarray is
still nil (used to crash, now return resp -1 and 0)

This file contains the implementation of the AnsiString type,
|
|
and all things that are needed for it.
|
|
AnsiString is defined as a 'silent' pchar :
|
|
a pchar that points to :
|
|
|
|
@-12 : Longint for maximum size;
|
|
@-8 : Longint for size;
|
|
@-4 : Longint for reference count;
|
|
@ : String + Terminating #0;
|
|
Pchar(Ansistring) is a valid typecast.
|
|
So AS[i] is converted to the address @AS+i-1.
|
|
|
|
Constants should be assigned a reference count of -1
|
|
Meaning that they can't be disposed of.

Revision 1.17 2001-08-01 15:00:10 jonas
|
|
+ "compproc" helpers
|
|
* renamed several helpers so that their name is the same as their
|
|
"public alias", which should facilitate the conversion of processor
|
|
specific code in the code generator to processor independent code
|
|
* some small fixes to the val_ansistring and val_widestring helpers
|
|
(always immediately exit if the source string is longer than 255
|
|
chars)
|
|
* fixed fpc_dynarray_high and fpc_dynarray_length if the dynarray is
|
|
still nil (used to crash, now return resp -1 and 0)
|
|
|
|
Revision 1.16 2001/07/10 18:04:37 peter
|
|
* merged textfile, readlink and concat ansistring fixes
|
|
|
|
Revision 1.15 2001/07/09 21:15:41 peter
|
|
* Length made internal
|
|
* Add array support for Length
|
|
|
|
Revision 1.14 2001/07/09 11:41:57 florian
|
|
* another MT fix
|
|
|
|
Revision 1.13 2001/07/08 21:00:18 peter
|
|
* various widestring updates, it works now mostly without charset
|
|
mapping supported
|
|
|
|
Revision 1.12 2001/07/04 12:17:09 jonas
|
|
* removed DestSize parameter from declaration of ValAnsiSignedInt64
|
|
(merged)
|
|
|
|
Revision 1.11 2001/05/27 14:28:44 florian
|
|
+ made the ref. couting MT safe
|
|
|
|
Revision 1.10 2001/04/13 18:06:07 peter
|
|
* upcase, lowercase for ansistring
|
|
|
|
Revision 1.9 2000/12/10 15:00:14 florian
|
|
* val for int64 hopefully works now correct
|
|
|
|
Revision 1.8 2000/12/08 14:04:43 jonas
|
|
+ added pos(char,ansistring), because there is also a pos(char,shortstring)
|
|
and without the ansistring version, the shortstring version is always
|
|
called when calling pos(char,pchar), even when using $h+ (because the
|
|
first parameter matches exactly) (merged)
|
|
|
|
Revision 1.7 2000/11/06 20:34:24 peter
|
|
* changed ver1_0 defines to temporary defs
|
|
|
|
Revision 1.6 2000/10/21 18:20:17 florian
|
|
* a lot of small changes:
|
|
- setlength is internal
|
|
- win32 graph unit extended
|
|
....
|
|
|
|
Revision 1.5 2000/08/29 18:39:42 peter
|
|
* fixed chararray to ansistring (merged)
|
|
|
|
Revision 1.4 2000/08/24 07:37:21 jonas
|
|
* fixed bug in setlength (it sometimes read after the end of the heap)
|
|
and small improvement to ansistring_to_chararray conversion (merged
|
|
from fixes branch)
|
|
|
|
Revision 1.3 2000/08/09 19:31:18 marco
|
|
* fixes for val(int64 or qword) to ansistring
|
|
|
|
Revision 1.2 2000/07/13 11:33:42 michael
|
|
+ removed logs
