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\&. .PP Definition at line 179 of file atomic_base\&.h\&. .SH "Author" .PP Generated automatically by Doxygen for libstdc++ from the source code\&.
