A C program can be linked with a C function with the HELP of the extern "C" linkage specification. The name MANGLING in C++ encodes all the codes into the symbol and therefore results in errors. Therefore, the references of these symbols should be avoided by the C COMPILER. One should have the KNOWLEDGE about the mangled function and type-safe linkages. During the compilation, with the extern "C" linkage specification, the name mangling feature is turned off to ensure the proper linkage of the C program to the C functions.
