Allocates the hContainer member of the TW_CAPABILITY structure to be type TW_ONEVALUE and fills it with the appropriate data.

When enumerating and getting capabilities, the toolkit takes care of creating the necessary TW_CAPABILITY containers. However, if the user wants to set a capability using the L_TwainSetCapability function, he or she must declare a TW_CAPABILITY container of the appropriate type (TW_ARRAY, TW_ENUMERATION, TW_RANGE, or TW_ONEVALUE).
