exit() #2 53 38 (2/14/2013 6:23:29 PM) comp.lang.c Can I use the return value provided to exit() for my own purposes? (This is so that I can pick up the exit-value when I invoke the program from another. BTW what's the best way of invoking a program under L... BartC

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... BartC

'Dynamic' function calls 27 44 (12/21/2012 10:13:25 PM) comp.lang.c I have a requirement to call a function where: o The function address is not known until runtime o Neither are the number and type of the parameters o Neither is the type of the function result o (And nei... BartC

Macros #8 29 37 (12/2/2012 5:53:27 PM) comp.lang.c I'm trying out these macros to save on typing and errors** : #define else } el##se { That seems to work: 'else' is converted to '} else {'. Somehow the ## stops the new 'else' from being recursively proc... BartC

inline functions #4 57 36 (11/24/2012 12:20:34 PM) comp.lang.c Is there a way of controlling which functions are inlined, or likely to be inlined, and which ones you never want inlined? Especially with gcc... (I have a file with over 300 functions, each of which is ca... BartC

'Unsigned decimal' 25 39 (11/2/2012 5:34:22 PM) comp.lang.c I have this code: int a = -2147483648; long long int b = 2147483648; And gcc gives me this warning for each: "warning: this decimal constant is unsigned only in ISO C90" These types are signed 32 a... BartC

function casts 28 24 (10/12/2012 9:42:27 PM) comp.lang.c Suppose I have a pointer to pointer to function like this: void (*(*fnptr)) (void); How do I apply this function signature as a cast to another type, say the variable p here: int *p; and call th... BartC

Function declarations #2 14 31 (9/28/2012 10:35:51 AM) comp.lang.c I have a C code generator that likes to insert lots of parentheses in type declarations (rather than truly understand how they work). But when declaring a function returning a pointer: int (*fn) (void);... BartC

gcc alignment options 19 38 (9/15/2012 11:57:44 PM) comp.lang.c I know this is considered off-topic but perhaps someone's got some ideas. I have a struct like this with elements all packed: #pragma pack(1) typedef struct s { short int a; char b; char c; int... BartC
