recvfrom function
may i ask why you were trying to find the remote address of a connection-oriented socket? if it is a client socket (i.e. you initiated the TCP connection with connect()), then you had to specify the address/port. if it is a server socket (i.e. returned by accept()), then the remote address and...- jorgander

how to find length of va_list string?
thanks for the reply. i was afraid i'd have to roll my own. -
how to find length of va_list string?
i've looked around for quite a while now, but can't find any reasonable solution for this. i'm trying to write a function that takes variable arguements (i.e. has char * fmt and '...' as two of its parameters), finds out how many bytes the resulting string formed by the arguement list will be... -
stack getting clobbered (value of esp)
sorry i haven't been on this forum in a while... yes, i solved the problem, and sadly it was my own naivette. u see, i am used to debugging non-assembler code with msvc++, and in the debugger when u are running a recursive function and u "step over" a function call, the debugger will... -
stack getting clobbered (value of esp)
something very strange when i'm debugging with msvc++ 6... if i step into every function call, esp doesn't get screwed up. however, if i step over a function call, it gets changed. to be more detailed, there are two sections of the recursive function, one to handle leaf nodes and one to... -
stack getting clobbered (value of esp)
i would have posted the code in the first place but it is kind of long. obviously there is something i'm not doing right, i just can't tell what it is. but as long as i know that nothing else *should* be happening to the stack, then i know it's a bug in my code and i can eventually find it, as... -
stack getting clobbered (value of esp)
i wrote a recursive function to search a tree structure, and i'm having problems with the code. the value of esp is not getting preserved over the recursive calls, but the strange thing is that as far as i can tell, upon every function entrance and corresponding function exit, the value is the... -
comparing unsigned 32-bit values
when i was first learning the instruction set, i didn't read the descriptions of all the different jumps. i just assumed there were more or less the same (e.g. ja and jg) and just had different mnemonics. when i read the fine print, it became a little clearer. -
comparing unsigned 32-bit values
never mind; i didn't know to use ja instead of jg, etc. -
comparing unsigned 32-bit values
i'm sort of a newbie to assembly, but have been a C programmer for a long time, so i'm not clueless about this stuff... that being said, i am trying to compare a value agaist -1, (that is, 4294967295). for some reason, the sign bit is not getting set when i do this. i've tried js and jl, but... -
affecting the alpha channel with GDI functions???
does anyone know how to get gdi functions (i.e. ellipse, textout, etc.) to draw to the alpha channel of a dc as well as the rgb channels? i'm already aware of the callback functionality with the LineDDA() function and that u can have your own function write to the alpha, but is it possible for...- jorgander
