1 2 This directory is for header files that are part of Native Client's 3 stable ABI, as exposed under Chromium by NaCl's IRT interfaces. It 4 defines how PPAPI is exposed to user code as a NaCl IRT interface. It 5 does not define PPAPI itself, whose stable ABI is defined by the 6 ppapi/c/ directory. 7 8 This directory only defines NaCl IRT interfaces that are specific to 9 Chromium's embedding of NaCl. Non-PPAPI-specific NaCl IRT 10 interfaces are defined in native_client/src/untrusted/irt/irt.h. 11
