The exception safe function library provides a consistent error handling mechanism that simplifies and centralizes error handling by using patterns such as error codes or exceptions, thereby making the program more robust and reducing redundancy. The usage steps include: selecting a function library that meets your needs (such as Boost.Exception, std::error_code, Google Abseil). Include necessary header files. Call appropriate functions based on the function library API to perform operations or handle errors.
How to use the exception-safe function library
The exception-safe function library is designed to handle exceptions and maintain program robustness while A collection of functions that provide consistent error handling. These libraries use error handling patterns, such as error codes or exceptions, and provide simplified and common error handling interfaces through them.
Benefits of using exception safe function library
Steps to use exception-safe function library
Practical case
Use the Boost.Exceptions function library to perform the following operations:
#include <boost/exception/all.hpp> int main() { try { // 执行可能引发异常的操作 } catch (const std::exception& e) { // 处理异常并执行恢复操作 std::cerr << e.what() << std::endl; return 1; } return 0; }
In the above example, the Boost.Exceptions function The library's exception handling mechanism is used to catch and handle any exceptions that may be thrown. Exception objects provide information about the cause of the error, allowing us to take appropriate recovery actions.
