bug #408 : prevent invalid data or crash by not reading beyond end of string
7 years ago
b66412f517
[PATCH] Changed prototypes of some functions having parameters that
should not be changed to const and added assorted comments. Also two very
minor efficiency improvements.

frontend/parser/lexical.c, cp_lexer(), allow # and * comment
Both, whether interactive or not.
Especially for command scripts.

input.c, simplify #ifdef for the broken visual studio _read()
If we have _MSC_VER so we have either CONSOLE HAS_WINGUI or SHARED_MODULE
If we have SHARED_MODULE, then we most certainly don't need
the unbuffered read(), which isn't unbuffered on _MSC_VER anyway.
Thus _MSC_VER is sufficient.

input.c, try to work around microsofts broken _read()
concerning the visual sudio variant of the "console" build.
Their _read() returns 0 when a linfeed is read.
Ironically the linefeed seems to be stored into the buffer nontheless.
Because the filehandle is in linebuffered mode anyway,
(the read won't return up until the terminating newline is entered)
we can just as well use getc(), which doesn't seem to suffer
from the same problem in their implementation.

lexical.c, change semantics of an ESCAPE in a given input `string'
now simply skip it.
presumably and in accordance to what the comments seems to suggest
ESCAPE never was really meant to be read as '['
but was replaced just to get it out of way deeper in the for loop
where an ESCAPE starts an ancient mechanism to reenter
interactive input via a terminals TIOCSTI capability
