)

Value:

0

A platform support query for testing if a supplied feature is defined.

Parameters

...	The name of the feature to query for.

Returns

if __has_feature is defined, the result of __has_feature(__VA_ARGS__), otherwise 0 .

Example usage testing for the address_sanitizer feature:

#if ARENE_HAS_FEATURE(address_sanitizer)

Note

__has_feature is a clang-specific facility. It generally shouldn't be used in user code, and instead should be used only as a building block to other platform support queries.
