This struct template implements a meta‐function for checking if a type is fundamental as defined in the C++11 standard [basic.fundamental]. Note that this is subtly differemt from bslmf::IsFundamental, which also returns true_type for references to fundamental types.

Synopsis

Declared in <bslmf_isfundamental.h>
