Other compiled languages that are commonly used for system programming other than C

We say0 CommentsTECHNOLOGYC++, Technology

Besides C, there are a few other compiled languages commonly used for system programming. Here are a couple of notable examples: C++: C++ is an extension of the C language and offers additional features, including object-oriented programming (OOP) capabilities. It is widely used in system programming for its ability to combine low-level control with high-level abstractions. C++ allows developers to write efficient and performance-critical code while benefiting from features like classes, templates, and exception handling. It is commonly used for developing operating systems, device drivers, embedded systems, and performance-critical applications. Rust: Rust is a relatively new systems programming language that…

Get SMBIOS physical address C/C++

We say0 CommentsTECHNOLOGYC++

The SMBIOS (System Management BIOS) physical address refers to the memory address where the SMBIOS table is located in the system's physical memory. The SMBIOS table contains information about the system's hardware components, such as the motherboard, processor, memory, and peripherals. To retrieve the SMBIOS physical address, you can use the WMI (Windows Management Instrumentation) API in Windows. Here's an example of how to obtain the SMBIOS physical address using C++ and the WMI API: #include <Windows.h> #include <iostream> int main() { IWbemLocator* pLocator = nullptr; IWbemServices* pServices = nullptr; // Initialize COM CoInitializeEx(NULL, COINIT_MULTITHREADED); // Create WMI locator HRESULT…

The functions “WmipFindSMBiosStructure” and “WmipSMBiosTablePhysicalAddress” C/C++

We say0 CommentsTECHNOLOGYC++

The functions "WmipFindSMBiosStructure" and "WmipSMBiosTablePhysicalAddress" are part of the Windows Management Instrumentation (WMI) API in Windows. They are used to retrieve information from the System Management BIOS (SMBIOS) tables. Here's a brief explanation of these functions: WmipFindSMBiosStructure: This function is used to search for a specific SMBIOS structure within the SMBIOS table. It takes parameters such as the structure type and index to identify the desired structure. The function returns a pointer to the found SMBIOS structure or NULL if the structure is not found. WmipSMBiosTablePhysicalAddress: This function retrieves the physical address of the SMBIOS table in memory. It returns…

Error ‘identifier’ : undeclared identifier in c++

We say0 CommentsTECHNOLOGYC++

The "identifier: undeclared identifier" error occurs when you use an identifier (such as a variable name, function name, or type name) that the compiler does not recognize or cannot find a declaration for. This error typically happens when you haven't properly declared or defined the identifier before using it. To fix this error, consider the following steps: Check the spelling: Make sure you have spelled the identifier correctly. Even a small typo can lead to this error. Declare the identifier: If you haven't declared the identifier before using it, you need to provide a declaration. This might involve adding a…

MEMORY_BASIC_INFORMATION undefined error in c++

We say0 CommentsTECHNOLOGYC++

If you are encountering an error stating that MEMORY_BASIC_INFORMATION is undefined in C++, it means that the identifier MEMORY_BASIC_INFORMATION is not recognized by the compiler. In C++, MEMORY_BASIC_INFORMATION is typically defined in the <windows.h> header file as part of the Windows API. Ensure that you have included this header file in your code. If you have included the <windows.h> header file and are still encountering the error, it is possible that you are missing a library or compiler directive. Check if there are any additional libraries that need to be linked against or if there are any specific compiler directives…

My main c++ program is not error but when compile so many libraries fail why? how to fix

We say0 CommentsTECHNOLOGYC++

If you are getting errors compiling your C++ program and there are too many library related errors, there are several possible causes and fixes: Missing header files or libraries: A common cause is missing header (.h) or library (.lib) files needed to compile and link your program. Make sure you have the associated library and header files installed and have specified the correct path so that the compiler and linker can find them. Version incompatibility: Sometimes, an incompatibility between a compiler's version and a library's version can cause an error. Check that the compiler version and the version of the…
