.SH "Detailed Description"
.PP 
Base type for atomic_flag\&. 

Base type is POD with data, allowing atomic_flag to derive from it and meet the standard layout type requirement\&. In addition to compatibility with a C interface, this allows different implementations of atomic_flag to use the same atomic operation functions, via a standard conversion to the __atomic_flag_base argument\&.
