New page

= The scl_union_activate pragma =

The scl_union_activate pragma provides a means to map discriminant values to specific union members. It can only apply to discriminated unions that have been identified by the scl_union pragma.

A single scl_union_activate pragma prescribes the set of values for the discriminant and the member that is active for those values.

== Syntax ==
#pragma scl_union_activate(container-specifier, union-member-specifier, constant-value-list)

{| border="1" cellspacing="0" cellpadding="10" style="align:left;"
| '''Parameters'''
| '''Type'''
| '''Description'''
|-
| ''container-specifier''
| Type
| Name of the structure encapsulating the union
|-
| ''union-member-specifier''
| Member
| The active member of the union
|-
| ''constant-value-list''
| Integer constant expression list
| List of the constant expressions that the discriminant takes on to activate the union member identified in this pragma
|}

== Notes ==
:* The discriminant field use in scl_union_activate must have already been identified with [[scl_union]].

== Examples ==
Use the following links to the scl_union page to see examples of the scl_union_activate pragma:
:* [[Scl_union#Example_3:_Explicit_mapping|Explicit mapping]]: Discriminant values are explicitly mapped to active union members using scl_union_activate().
:* [[Scl_union#Example_8:_Explicit_mapping_of_multiple_discriminant_values_to_a_single_active_member|Explicit mapping of multiple discriminant values to a single active member]].
:* [[Scl_union#Example_9:_Unmapped_discriminant_values_indicating_no_member_is_active|Unmapped discriminant values indicating no member is active]].
:* [[Scl_union#Example_10:_Discriminant_values_defined_by_macros|Discriminant values defined by macros]].
