memset() works on raw memory, so you filled the bytes of 'a' with the value 50, which in turn makes every double value in a be 0x3232323232323232, which who knows what that is. If you want to fill 'a' with doubles having the value 50.0, you should use std::fill(). ...
how i use memset()? heres my actual code: 1234 if(Pixels==NULL)VirtualFree(Pixels, 0,MEM_RELEASE);; unsigned int PixelsCount =SizeWidth*SizeHeight*sizeof(unsigned int); Pixels = (unsigned int*) VirtualAlloc(0, PixelsCount,MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE); memset(Pixels,NewColor...
In response to MotooTanaka Hi, thank you for answer. I want to use printf() family in situation something like this: void UART_printf(char *arg_list, ...) { va_list arg_buffer; va_start(arg_buffer, arg_list); memset(uart_printf_buf, 0, sizeof(uart_printf_buf)); vsprintf(...
Use thegetnameinfoFunction to IP Address to Host Name in C Thegetnameinfofunction is used in conjunction withgetaddrinfoin this case, and it retrieves the hostnames for corresponding IP addresses. Notice that we process the user input from the first command-line argument and pass it as theget...

In this example, we use aforloop to iterate over each element of the array and set it to the null character\0. This achieves the same result as usingmemset(). #include<stdio.h>#defineARRAY_LENGTH 10voidclearArray(chararr[],size_t len){for(size_t i=0;i<len;i++){arr[i]='\0...
memset(buf, ch, sizeof(buf)); if (isupper(ch)) { nSize = send(myOOBSocket, buf, sizeof(buf), 0); //Do not use the MSG_OOB flag. Send it as normal data. } else { nSize = send(myNormalSocket, buf, sizeof(buf), 0); ...
To parse an XML file, we need to declare like: Parser.parse() .getXMLRoot(); Destructor: XmlDomDocument:: document() { Doc->release(); } When parsing in Visual Studio, C++ speed is taken into account as the memory allocation is very less. One can use this environment and may conside...

Well, in that case I suggest you adopt Pavel A's suggestion. Do you mean I have to assign my variable to unsigned int variable and then I have to pass it to the function? Pavel A suggested that you pass the member of the union that is an unsigned int. Changes to the value o...
