withObjects

Creates and initializes an OSSet populated with objects provided.

Declaration

static OSSetPtr withObjects(const OSObject **values, uint32_t count, uint32_t capacity);

Parameters

  • values:

    A C array of OSMetaClassBase-derived objects.

  • count:

    The number of objects to be placed into the set.

  • capacity:

    The initial storage capacity of the new set object. If 0, count is used; otherwise this value must be greater than or equal to count.

Return Value

An instance of OSSet containing the objects provided, with a retain count of 1; NULL on failure.

Discussion

objects must be non-NULL, and count must be nonzero. If capacity is nonzero, it must be greater than or equal to count. The new OSSet will grow as needed to accommodate more objects (unlikeCFMutableSet, for which the initial capacity is a hard limit).

The objects in objects are retained for storage in the new set, not copied.
