void func()返回值?
嘿,
请考虑以下代码:
void func(void)
{
}
void func2(无效)
{
return func();
}
gcc -pedantic说如下:
muntyan @ munt10:/ tmp $ gcc -pedantic -c file。 c
file.c:在函数中?func2?:
file.c:7:警告:?返回?有一个值,在函数中返回void
如果我没记错的话,一些Microsoft Visual Studio版本中的编译器
告诉了我同样的事情。那么,这是一个编译器错误(功能),还是这个
" return func();"标准C无效?
谢谢,
Yevgen
Hey,
Consider the following code:
void func (void)
{
}
void func2 (void)
{
return func ();
}
gcc -pedantic says the following:
muntyan@munt10:/tmp$ gcc -pedantic -c file.c
file.c: In function ?func2?:
file.c:7: warning: ?return? with a value, in function returning void
If I recall correctly, compiler in some Microsoft Visual Studio version
told me the same thing. So, is this a compiler bug (feature), or is this
"return func ();" invalid in standard C?
Thanks,
Yevgen

它在标准C中是无效的。也许你在想C ++,它允许在哪个
?
It''s invalid in standard C. Perhaps you''re thinking of C++, where it is
allowed?
