I can't immediately think of a reason why no C program would be valid C++ without modification (especially now that the standardization committee decided that standard headers inherited from C with names in the form of <name.h> are valid and will put everything in the global namespace.) |

I'm more interested in why people /care/. This topic generates a lot of heat, over and over again ... but as I see it, pretty much everyone[0] has a C compiler and a C++ compiler, and will compile their C code with the former and their C++ code with the latter. The ability to use C libraries from C++ (without any glue) matters though. /Jorgen [0] Not everyone. -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o . |

One common reason is that C code typically doesn't cast the result of malloc(), but C++ does not permit implicit conversion from void* to (other) object pointer types. Another is that C++ string literals are const, so this: char *s = "hello"; is invalid C++. A less common reason might be C code that uses C++ keywords as identifiers.

Big time. It would be nice to have a destructor in there to automatically destruct the vector, ahh shit!, std::vector. ;^) |

Using linux makes a great router. SCTP is available for Linux. Raspberry Pi runs Linux. Some models of Raspberry Pi have WiFi built in (admittedly with limited range, but should be enough for a wireless repeater if you need that). If you need a real network center, couple the Raspberry Pi with a multilayer managed switch. Cisco SG350-10 is available on Amazon for $144. |

One alternative I've found is https://www.bhphotovideo.com . Their prices are often better than Amazon's if you have their card. I should add them to my recommended sites page.

| cdalten@gmail.com: Apr 25 12:34PM -0700 Some of you might not realize this, but Dan Cross is bisexual. He is currently married to a woman. But he always had feeling for his ex boyfriend Chuck Martin. Anyways, Dan hasn't really been himself since Chuck passed away a few days ago. I'm sure Dan would appreciate it if you emailed him at crossd@gmail.com and tell him that he will meet his ex boyfriend again in heaven. |

You know int will work, without having to worry about possible incongruities between _Bool/bool, headers, etc. Also, if the parameter type is bool, then because of conversion rules it would be allowed to pass pointers as arguments. My guess is you don't want to allow passing pointers as arguments. |

But > is "_Bool" just a regular 'int' or is it something smaller (e.g. char)? Use the first one. And if you feel it necessary, add something like #ifdef __cplusplus static_assert( c_bool_size = sizeof( bool ) );
