When to use a .C library vs a .CPP library

i copying wiring_serial library testing.  i want create new "test_serial" mods.  hopefully avoids risks of continuing edit core code.  

my question is, hardwareserial.cpp appears call "wiring.serial.c"  presumably put c++ face on it.   there reason cannot make new library .cpp start with?  it looks can hook interrupts in .cpp.   or matter there problem creating .c library , distributing it?

feel free make libraries written in c++.  i think existing libraries don't go out , make c++ syntax less confusing newcomers or c programmers, c++ can serve needs of small programs c.

if you're going make c library functions usable user's c++ sketch, need ensure header file explicit c nature.

mylibrarywritteninc.h

code: [select]


[glow]#ifdef __cplusplus
extern c {
#endif[/glow]

/* prototypes functions implemented in c */
int mycfunction(float, char, int);

[glow]#ifdef __cplusplus
} // extern c
#endif[/glow]
