Second, write a wrapper library in C++ that calls all the functions in C format, or third, tell the C++ compiler that you are calling a "C" function so that it won't decorate the names.

To be able to call C library functions both from C and C++ code, it's
customary to wrap the function declarations in the library header(s)
like that:

"""
#ifdef __cplusplus
extern "C" {
#endif

// function declarations
...

#ifdef __cplusplus
}
#endif
"""
