C scope and struct definitions 71 51 (6/22/2012 5:30:41 PM) comp.lang.c The discussion about scope in the "What a stupid gcc" thread reminded me of the one time (that I recall) where I was bitten by this. I don't recall the specifics, but it had to do with a function that was ... Kenneth

Rejecting connection attempts on socket 15 112 (5/22/2012 4:02:07 PM) comp.unix.programmer I've searched and searched, and I have a feeling the answer is "you can't", but I figured I'd ask here just in case I missed something. I have a socket, I've bound it to a port, and entered a listening state.... Kenneth

Expanding macros within #error 3 41 (12/22/2011 7:55:03 PM) comp.lang.c Is it possible to have #error expand macros? For example, something like: #if FOO == 1 ... something ... #elif FOO == 2 ... something else ... #elif #error Unknown value of FOO -- [value of ... Kenneth

Unions / unsigned char[] 5 34 (9/8/2011 4:28:21 PM) comp.lang.c Okay, I can't find C&V, but as I recall, accessing a union via anything other than the one last written to is UB. For example: my_union.my_int = i; f = my_union.my_float; However, I believe that y... Kenneth

Random thought -- EOF and errno 27 24 (8/12/2011 4:04:43 PM) comp.lang.c A stray thought wandered into my head this morning... Given that 7.5p4 reserves macros that begin with E+digit or E+capital-letter for error codes, what allows the Standard to also define EOF in a manner unr... Kenneth

Version-checking macro 9 40 (7/8/2011 6:42:28 PM) comp.lang.c This is one of those "it works on my compiler, but I want to verify that it's 'legal and defined' as far as C is concerned" types of things. I am writing a macro which I will be using as a version check, as i... Kenneth

volatile parameters and returns 2 339 (8/4/2010 1:09:03 PM) comp.lang.c The thread "volatile Info" posed a question about a function with a volatile parameter. At first, I was surprised that the syntax was even valid. (I suppose it's more of "why should the Standard prohibit ... Kenneth

Forcing compile-time error 10 132 (6/11/2010 1:53:11 PM) comp.lang.c I know about the #error directive, but it can't be used in this case... I am replacing calls to an outdated system function with a new wrapper function which can be updated as needed. (ie: if the "new" sy... Kenneth

Darn default-int (minor vent) 15 36 (9/24/2009 3:08:22 PM) comp.lang.c So, whose idea was "default int"? I just fixed a bug resulting from "someone" changing: register char *p1, *p2; to register char *p1; register *p2; Not a peep from the compiler. Fortunately, ... Kenneth

Functions not matching prototypes, redux 7 30 (5/13/2009 4:38:41 PM) comp.lang.c Okay, here's a variation on my question posted previously under the subject "Why is this not an error in Visual C?" Here is a new source file: ===== extern int foo(void); int before(void) { ... Kenneth

Command line arguments 136 31 (1/10/2013 8:58:16 PM) comp.lang.c I've just discovered that a single command line argument containing wildcards, such as *.c, is expanded to a full list of matching files before it gets to main(). That isn't really what I want (and there c... bc (2211)
