Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_typeid_is_collection() function determines whether a type identifier is for a collection.

mi_boolean mi_typeid_is_collection(typeid_ptr)

MI_TYPEID *typeid_ptr;

typeid_ptr

is a pointer to the type identifier to check.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
Yes	Yes

The mi_typeid_is_collection() function determines if the data type in the type identifier that typeid_ptr references is a collection data type. Valid collection data types are SET, MULTISET, and LIST.

Important: The type identifier is an opaque structure. Do not access its value directly. To determine if a type identifier contains a collection data type, always use mi_typeid_is_collection().

Return Values

MI_TRUE	indicates that the type identifier that typeid_ptr indicates is a collection type.
MI_FALSE	indicates that the type identifier that typeid_ptr indicates is not a collection type.

See the descriptions of the following functions: mi_typeid_equals(), mi_typeid_is_builtin(), mi_typeid_is_complex(), mi_typeid_is_distinct(), mi_typeid_is_list(), mi_typeid_is_multiset(), mi_typeid_is_row(), and mi_typeid_is_set().
