gtk:bitset-size (bitset)

bitset -- a gtk:bitset instance

The unsigned integer with the number of values in bitset.

Gets the number of values that were added to the bitset. For example, if the bitset is empty, 0 is returned. Note that this function returns an unsigned 64-bit integer, because when all values are set, the return value is #xffffffff + 1. Unless you are sure this cannot happen, it cannot with the g:list-model object, be sure to use a 64-bit integer type.
