Sorry, but what do you mean by "Class std::string has value semantics"?

It seems to me that you have a C background. Right? That's why you feel uneasy about this approach. It is strange indeed. Thanks for the answer.

In the following class I'm using the C lib <time.h> . The functions gmtime, ctime, and asctime return pointers to char/structs. Am I responsible to clean the memory allocated by them? Is there any possible memory leak associated to the methods MyTimeClass::getDateAndTimeLocalTime() and...

There are 4 tables defined in this MIB: - Config Table: which holds configurations profiles for named Logs. -Stats table : which holds statistical data for each named log. -Log table: which holds the actual log entries for each named log. - LogVariableTable: which keeps track of log table...

Thanks Scott, but that’s the point. I can’t change things like that. Unfortunately this is a legacy code and I need to figure out a way to use those structures as they are. Would be very nice to have u_int8_t *data instead of u_int8_t data[MAX_DATA_SIZE]. Best Regards, P.

I’ve got an equipment that receives some data from the network and map it to the structures below: struct a_s{ u_int16_t cmd; u_int16_t dataSize; u_int8_t data[MAX_DATA_SIZE]; }; typedef struct a_s a_t; struct b_s { u_int16_t part; u_int16_t serial; a_t payload; }; typedef struct...

That wouldn't cause some memory leak? Since it's automatically allocated a chunk of memory of u_int8t * MAX_DATA_SIZE bytes?

Here is an excerpt from one tutorial on how to compare float numbers in C: "(...) It is very usual for the C programming language beginners to compare a floating point number using the "==" operator. Floating point numbers must not be compared with the "==" operator. That is mainly because...

Given the following scenario: struct a_s{ u_int16_t cmd; u_int16_t dataSize; u_int8_t data[MAX_DATA_SIZE]; }; typedef struct a_s a_t; struct b_s { u_int16_t part; u_int16_t serial; a_t payload; }; typedef struct b_s b_t; (...) b_t message; how can I set...

class Parent { public: virtual void functionA() = 0; virtual void functionB() = 0; }; class SonA : public Parent { public: //implements virtual methods void functionA(); //... void functionB(); //... //SonA's exclusive method void exclusiveMethodSonA(); }; class SonB ...

Thanks for the reply. It turned out that the 'func(pu)' was actually a macro. Regards.

Hi, Is that a function definition? Why there are 2 sets of '()' in the definition and in the call? What's the name of this kind of definition? Definition: static inline void func(pu) ( void ) { printf( "%s", s_msg_usage ); } Call: func(pu)(); Thanks.

In the following code why does the pointer head is still null after function calling? Thanks. #include <stdio.h> #include <stdlib.h> struct list_element{ int info; struct list_element * next; }; typedef struct list_element item; void alloc(item *head){ printf("%p\n"...

Does anyone have a algorithm for drawing a b-tree (a multiway tree, not a binary tree) on the canvas? I'm having a really hard time trying to do that! Thanks, Best regards, Paul.
