Detailed Description

Represents a linkage specification.

For example:

extern "C" void foo();

Definition at line 2523 of file DeclCXX.h.

Member Enumeration Documentation

Represents the language in a linkage specification.

The values are part of the serialization ABI for ASTs and cannot be changed without altering that ABI. To help ensure a stable ABI for this, we choose the DW_LANG_ encodings from the dwarf standard.
