If I were coding this in C I'd probably do something like (warning:
untested code I'm making up on the spot out of the dim recesses of my
memory):
char *FindEndOfFirstLine(char *pText)
{
char *pChar;
while(*pChar++)
{
if('\n' == *pChar)
{
// *++pChar = 0;
break;
}
}
return pChar;
}
char *FindLastLine(char *pText)
{
char *pChar;
pChar = pText;
pText += length(pText);
if('\n' == *pChar)
pChar--;
while('\n' != *pChar--)
{
if (pChar == pText)
break;
}
// *++pChar = 0;
return pChar;
}
So I'd allow a little extra time for the length() call, but I wouldn't
expect an order of magnitude difference.
