2014/1/14-2/5 [Computer/SW/Languages/C_Cplusplus] UID:54763 Activity:nil | 1/14 Why is NULL defined to be "0" in C++ instead of "((void *) 0)" like in
C? I have some overloaded functtions where one takes an integer
parameter and the other a pointer parameter. When I call it with
"NULL", the compiler matches it with the integer version instead of
the pointer version which is a problem. Other funny effect is that
sizeof(NULL) is different from sizeof(myPtr). Thanks.

at UCB ugrad cs, probably replaced emacs. Furthermore, people get
angry at seeing Makefiles, (since eclispe takes care of that). I
guess it's just a sign of the times.

managable in emacs. I'm not sure which application's fault

doesn't happen. Any idea? Thanks.

2006/1/25-27 [Computer/HW/Memory] UID:41522 Activity:nil | 1/25 I'm working on a program in windows which is having memory problems.
When I allocate memory with new or malloc, it seems to reserve more
memory than I request (using VM Valiator to monitor this). Even if I
delete the memory there is still a "reserved" chunk that doesn't seem
to ever get used by other code. I'm using VC++ 6 btw. Anyone have an
idea of what might be going on?

single-threaded signal based server. He's using the icc compiler
on 64-bit linux. However, the following problem comes up. The
server is working and calls malloc. Malloc grabs the allocation
mutex (thread-safe!), then a signal comes in. The signal
interrupts malloc and calls the handler function. The handler

2005/2/15-16 [Computer/SW/Languages/C_Cplusplus, Computer/SW/Compilers] UID:36174 Activity:moderate | 2/15 Technical question: we have a memory leak in our C code, we think,
but it's not the sort of memory leak where the memory's unreferenced.
What we'd like to do is sort of a poor-man's profile, we want
to know who calls our memory allocator "New"... Sorta like a stack
trace. Using an actual profiler is sort of difficult 'cause it's
a parallel application. Thanks, --peterm

2004/12/8-9 [Computer/SW/Languages/C_Cplusplus, Computer/SW/Languages] UID:35217 Activity:kinda low | 12/8 When people say null string or empty string in C, does it mean a char
pointer that's NULL, or a char array whose first char is '\0'? Thanks.
\_ Both, because it's essentially the same. However, I think they
probably mean the latter. I assume you mean a pointer pointing
to NULL, and not a pointer which is NULL, which makes no real
sense.
