Hello, Kir,
Do you know, at least something about what the following code from
charset.cpp mean?
Is it some kind of hashing? Why is the assignement repeated twice?
void MakeWordRange(TCHARSET* charset)
{
mdemset(charset->wordch, 0, sizeof(charset->wordch));
unsigned char* pc = charset->chars;
while (*pc)
{
charset->wordch[*pc >> 3] |= (1 << (*pc & 7));
pc++;
}
pc = (unsigned char*)WORDCHAR;
while (*pc)
{
charset->wordch[*pc >> 3] |= (1 << (*pc & 7));
pc++;
}
}
and
int WordChar(unsigned char s, int charset)
{
return Charsets[charset].wordch[s >> 3] & (1 << (s & 7)) ? 1 : 0;
}
