dbr_size_n(TYPE, COUNT)

Returns the size in bytes for a DBR_XXXX type with COUNT elements.

If the DBR type is a structure then the value field is the last field in the structure. If COUNT is greater than one then COUNT-1 elements are appended to the end of the structure so that they can be addressed as an array through a pointer to the value field.

See also

dbr_size, dbr_value_size

Parameters:

TYPE – [in] The data type.
COUNT – [in] The element count.

Returns:

The size in bytes of the specified type with the specified number of elements.

Parameters:

type – [in] The data type code. A member of the set of DBR_XXXX in db_access.h.

Returns:

The const string corresponding to the DBR_XXXX type.
