test.cpp:7: int getArrayValue(std::array<int, 10ul>, int): Assertion `index >=0 && index <=9' failed. 如何给断言语句添加额外的描述信息 有时断言语句的描述信息不够清晰,比如考虑如下这种情况: assert(found); 如果这个断言被触发,那么会得到类似于如下的错误信息: file_name:line_number : func...

in file foo.c, function do_bar(), line 1287" is of no help at all to a user.RETURN VALUENo value is returned.ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).Manual page assert(3) line 1 (press h for help or q to quit)从man手册中可以知道的是as...
在C的assert.h头文件中。 assert宏的原型定义在<assert.h>中,其作用是如果它的条件返回错误,则终止程序执行。 assert的细节是先计算表达式expr,如果其值为假(即为0),那么它会打印出来assert的内容和__FILE__,LINE, __ASSERT_FUNCTION,然后执行abort()函数使kernel杀掉自己并coredump(是否生成coredump文件,取决于...
__PRETTY_FUNCTION__是当前的函数名,可以获取更为详细的函数信息 #e是将后面的参数进行字符串化操作,即"e" 这样看和我们之前看到的报错打印信息对应上: test: test.cpp:14: void printNum(int*): Assertion `num != nullptr' failed. 1. 最后我们看看async_safe_fatal的实现: ...
The _RPT and _RPTF group of macros is also exercised in this program, as an alternative to the printf function. C Copy // crt_ASSERT_macro.c // compile with: /D_DEBUG /MTd /Od /Zi /link /verbose:lib /debug // // This program uses the _ASSERT and _ASSERTE debugging macros. ...
In a Windows-based application, assert calls the Windows MessageBox function to create a message box to display the message with three buttons: Abort, Retry, and Ignore. If the user chooses Abort, the program aborts immediately. If the user chooses Retry, the debugger is called, and the ...
任务并发调度(Function Flow Runtime) 如何在Native侧C++子线程直接调用ArkTS接口,不用通过ArkTS侧触发回调 ArkTS层调用Native层接口时的线程相关问题 Native侧获取env具有线程限制,如何在C++子线程触发ArkTS侧回调 如何在C++调用从ArkTS传递过来的function 如何在Native侧调用ArkTS侧异步方法,并获取异步计算结果...
Arguably, unused return values are better of detected by the compiler. For instance GCC and Clang allow you to mark function with attributes: __attribute__((warn_unused_result)) int foo(); Which will emit the following warning in case the return value is not used: ...
In this program, theanalyze_stringfunction uses theassertmacro to test several conditions related to string and length. If any of the conditions fails, the program prints a message indicating what caused the failure. C // crt_assert.c// compile by using: cl /W4 crt_assert.c#include<stdio....
