int STkeyMatch (const char String, const char *KeyTable)
Match a string to keyword strings
This subroutine searches a table for a match to a character string. The
table of keywords is searched for the first match. The keyword table can
optionally specify the minimum length for a match and a length beyond which
characters need no longer match. The keywords are searched in order.
Each entry of the keyword table specifies the character string to be matched.
An optional asterisk ('*') is used to indicate the minimum number of
characters needed for a match. A second asterisk can be used to indicate
that characters after this point need not match.
Keyword table entry "abc*de*f". Input strings "abc", "abcd", "abcde", and
"abcdex" will match this entry. Input strings "ab", "abC" " abc" and
"abcx" do not match this entry.
<- int STkeyMatch
Index of the matched keyword. This value is set to -1 if no match is
-1 - No match
0 - Match to the first keyword
1 - Match to the second keyword
-> const char String
Input character string. If String is the NULL pointer, a no match
condition is returned.
-> const char *KeyTable
Pointer array with pointers to the keyword strings. The end of the
keyword table is signalled with a NULL pointer. Note that with ANSI C,
if the actual parameter is not declared to have the const attribute, an
explicit cast to (const char **) is required.
