cgGetParameterResourceSize

> # NAME

> cgGetParameterResourceSize - get size of resource associated with a parameter

> # SYNOPSIS

>       #include <Cg/cg.h>

>       long cgGetParameterResourceSize( CGparameter param );

> # PARAMETERS

> param

>   The parameter for which the associated resource size will be retrieved.

> # RETURN VALUES

> Returns the size on the GPU of the resource associated with param.

> Returns -1 if an error occurs.

> # DESCRIPTION

> cgGetParameterResourceSize returns the size in bytes of the resource corresponding to a parameter if the parameter belongs to a Cg buffer resource.

> The size of sampler parameters is zero because they have no actual data storage.

> The size of an array parameter is the size of an array element parameter times the length of the array.

> The size of a structure parameter is the sum of the size of all the members of the structure plus zero or more bytes of profile-dependent padding.

> # EXAMPLES

> to-be-written

> # ERRORS

> CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

> # HISTORY

> cgGetParameterResourceSize was introduced in Cg 2.0.
