okutil_find_strings
Description
Finds all strings in an array that match a given test string. The test string may contain wild characters * and ?.
Syntax
int okutil_find_strings( StringArray * psaFound, StringArray * psaSearch, LPCSTR lpszFindThis, DWORD dwOptions = OFS_MATCH_WHOLE_STRING, IntArray* pnIndex = NULL )
Parameters
- psaFound
- [output] an array containing strings from the original array that match the test string lpszFindThis. Can be NULL if you want just the number of matches.
- psaSearch
- [output] the array of strings to be searched.
- lpszFindThis
- [input] the test string to find. It may contain wild characters * and ?.
- dwOptions
- [input] Can be 0x0, or you can 'OR' together any of the following:
- OFS_CASE_SENSITIVE the match must be case sensitive
- OFS_WILDCHARS_OFF interpret wild characters * and ? as literals, not wild characters.
- OFS_MATCH_START_STRING the test string must match the beginning of the searched string. If there are wild characters (and OFS_WILDCHARS_OFF is not set), then OFS_MATCH_START_STRING has no affect.
- OFS_MATCH_WHOLE_STRING the test string must equal the searched string (up to case, which is controlled by OFS_CASE_SENSITIVE). If there are wild characters (and OFS_WILDCHARS_OFF is not set), then OFS_MATCH_START_STRING has no affect.
- pnIndex
- [output] an array containing item indices of the original array that match the test string lpszFindThis. Can be NULL.
Return
the number of matches found.
