intprintf(constchar*format,...);intmain(){printf("I'm learning the use of Extern in C++");} We use theexternkeyword in C++ programming to eliminate this issue. Whenever the C++ compiler finds the code inside theextern "C" {}block, it makes sure that the name of the function remains...
However, semihosting can be extremely slow. Another good option is to output debug information over the serial port (UART). We can call the STM32 HAL functions (e.g. HAL_UART_Transmit), but sometimes it’s easier to use the standard C library functions printf, scanf, and so on. To do...
That's not actually an answer to the question. Read the arguments to VirtualAlloc() in the question again: the two allocations use two different ranges of pages. I'm having a similar problem, where code that walks the virtual space calling VirtualAlloc() with specific base addresses fails to...
Next, we use the printf() function, which is part of the C standard input-output library. It allows us to perform formatted output. In this case, we use the format specifier %s to indicate that we want to print a string. To use printf() with a C++ string, we must call the c_str...
case1:printf("Input: %s\n", result->str);printf("Result: %ld\n", result->result);return; This lets us read thechar *strpointer. If we could control the value ofstr, we could use this to arbitrary read. 3.2. "Delete result" ...

Optionally, for an absent device, call the CM_Get_Device_ID function to obtain the device instance ID and to display the ID before you remove the information. For the absent device, use the class information that you obtained in step 1 and the instance...
In this section we will discuss on how to call C functions from C++ code. Here is the C code (Cfile.c): #include <stdio.h> void f(void) { printf("\n This is a C code\n"); } The first step is to create a library of this C code. The following steps create a shared librar...
