int Ns_SetFind(
Ns_Set *set,
char *key
);
The Ns_SetFind function returns the index of the first field whose key name matches the given key. The index is in C array order, i.e., 0 is the index of the first field. If no fields are found, Ns_SetFind returns -1. If more than one field in the set has the same key name, Ns_SetFind returns just the first field index.
The Ns_SetIFind function is this function's case-insensitive counterpart.
Ns_Set *aSet;
int index;
aSet = Ns_SetCreate("");
Ns_SetPut(aSet, "Foo", "foovalue");
Ns_SetPut(aSet, "Bar", "barvalue");
index = Ns_SetFind(aSet, "Foo"); /* case sensitive search*/
if (index == -1) {
Ns_Log(Warning, "set key Foo not found");
} else {
Ns_Log(Notice, "Value for Foo is %s",
Ns_SetGet(aSet, "Foo"));
}
Ns_SetFree(aSet);
