void format_SaNameT( const char* const name, SaNameT* formatted )
{
   if( ! name || ! formatted ) return;

   memset( formatted, 0, sizeof( SaNameT ) );
   formatted->length = strlen( name );
   strncpy( formatted->value, name, SA_MAX_NAME_LENGTH );
}

这里“format_SaNameT”显示警告

最佳答案

您应该在头文件中提供一个原型，以便编译器知道它在处理什么。。。
在不同的void format_SaNameT(const char* const, SaNameT*);文件或主文件中声明.h，警告将消失。
