FindStrInStr
Purpose: Perform a case-blind partial word search for a string in another
string. This function assumes that the string to find is in lower-case
characters.
Prototype: Boolean FindStrInStr (const CharPtr strToSearch,
const CharPtr strToFind, const WordPtr posP)
Parameters:
strToSearch = String to search.
strToFind = Converted, caseless version of the ASCII text string to be
found.
posP = Pointer to offset in search string of the match.
Result: Returns true if the string was found. FindStrInStr matches the
beginnings of words only; that is, strToFind must be a prefix of
one of the words in strToSearch for FindStrInStr to return
true.
Comment: Don't use this function on systems that support the Text Manager.
Instead, use TxtFindString, which performs searches on strings
that contain multi-byte characters and returns the length of the
matching text.
On systems that don't support the Text Manager, use Use
GetCharCaselessValue to convert a string into the appropriate
format for strToFind in code similar to the following:
CharPtr origStr;
/* Standard null-terminated ascii string */
CharPtr strToFind;
/* Converted string to be passed to */
/* FindStrInStr */
BytePtr convTab;
/* Conversion table returned from */
/* GetCharCaselessValue*/
Word i;
convTab = GetCharCaselessValue();
for (i=0; origStr[i] != 0; i++)
{
strToFind[i] = convTab[origStr[i]];
}
strToFind[i] = 0;
/* Now pass strToFind to FindStrInStr...*/
Note that the strToFind element of the parameter block passed by
the system's Find utility is preconverted, so it can be passed straight
through to FindStrInStr.

I try to use the function FindStrInStr, but I don't find the right function
that convert a text into the right format for this function.
