4.6.1 g-value-zero

— Function: g-value-zero
     (g-value-zero g-value)
g-value
A foreign pointer to GValue structure.

Initializes the GValue to "unset" state. Equivalent of the following initializer in C:

     GValue value = { 0 };

Must be called before other functions that work with GValue (except set-g-value with keyword argument :zero-g-value set to true).
