Summary
StrNScan returns the length of the consecutive characters in S1 which do not appear in S2.
Pascal
function StrNScanW(const Str1: PWideChar; const Str2: PWideChar): SizeInt;
Parameters
| Parameters | Description |
| S1 | The source string. |
| S2 | The sequence (set) of characters to test against. |
Description
StrNScan returns the length of the consecutive characters in S1, from the start of the string, which do not appear in S2. In other words: StrNScan returns the length of the longest sequence in S1 for which the predicate "not (S1^ in S2)" holds true if S2 were to be considered a set of characters. As an example consider S1 to hold 'Project JEDI' and S2 to hold 'abcdef'. Calling StrNScan with these parameters will return 4 since the fifth character, an 'e', appears in S2.
