Gck.Attributes.prototype.find_ulong

function find_ulong(attr_type: Number(gulong)): [ok: Boolean, value: Number(gulong)] {
    // Gjs wrapper for gck_attributes_find_ulong()
}

Find an attribute with the specified type in the array.

The attribute (if found) must be of the right size to store a unsigned long value (ie: CK_ULONG). If the attribute is marked invalid then it will be treated as not found.

attr_type: The type of attribute to find.
ok: Whether a value was found or not.
value: The resulting gulong value.
