Function

CFSetGetCountOfValue

Returns the number of values in a set that match a given value.

Declaration

CFIndex CFSetGetCountOfValue(CFSetRef theSet, const void *value);

Parameters

theSet

The set to examine.

value

The value for which to search in theSet. Comparisons are made using the equal callback provided when theSet was created. If the equal callback was NULL, pointer equality (in C, ==) is used.

Return Value

The number of times value occurs in theSet. By definition, sets can not contain duplicate values, so returns 1 if value is contained in theSet, otherwise 0.

Discussion

This function uses the equal callback. value and all elements in the set must be understood by the equal callback.
