L_LTTWN_API L_INT L_TwainCreateNumericContainerOneValue (pCapability, Type, uValue)

TW_CAPABILITY * pCapability;	/* pointer to a structure */
LTWAINNUMERICTYPE Type;	/* container type */
L_UINT_PTR uValue;	/* TW_ONEVALUE value */

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

Parameter	Description
pCapability	Pointer to a structure that contains the capability container to allocate as type TW_ONEVALUE.
Type	Type of data contained in the TW_ONEVALUE container. For a list of possible values, refer to LTWAINNUMERICTYPE.
uValue	Value of the TW_ONEVALUE structure.

Comments

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).
