C ++中的范围_t尾名称

Question

Does the rule about _t-ending names being reserved also apply to scoped names (eg, types and typedefs defined within namespaces or within classes) or is it just for types and typedefs in the global namespace? Could an implementation of a standard C/C++ library or a POSIX library ever use these names as macros in its headers? (If it could, then I think that answers the first question).

Answer 1

POSIX保留以“ _t”结尾的名称（据我所知，在任何上下文中）（ http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html ），因此如果出现以下情况，则不应在任何上下文中使用它们您的目标是POSIX系统（几乎可以归结为“不使用它们”）。
