Sometimes you just need to ask a question in order for the answer to
become obvious. **p == '[', but *p == a char const*, duh.
Page fault with isspace(*p)
I am rewriting the regsvr stuff in dlls/comcat to make it practical to
extend to ole32 and all the other COM DLLs. I have a nice simple function
to skip whitespace and return the next character:
static int getc_skipws(char const **p)
{
while (isspace(*p))
++*p;
return **p;
}
This gets called with **p == '['. I get a page fault in the
implementation of isspace(), where the macro is testing 0x20 against the
value for '[' in the __ctype_b array. What gives?
