how write namespace need each other? this:
namespace amxe { void register(amx *amx); void release(amx *amx); struct s_amxe { command::s_command command; }; extern std::unordered_map<amx*, s_amxe*> *list; } namespace command { extern dword onplayercommandtext_addr; void initialize(); void registerallfromamx(amx* amx, amxe::s_amxe* amxdata); cell command_addaltnamed_n(amx *amx, cell *params); struct s_command { int onplayercommandreceived; int onplayercommandperformed; }; } when compile code, got warning command not namespace in "command::s_command command;" line.
the definition of command::s_command not available when use:
struct s_amxe { command::s_command command; }; it makes sense compiler throws error @ line.
you can forward declare names (classes, functions, etc.) inside namespaces can forward declare global names.
after can use pointers , references types. however, use object of class in namespace, class must defined first.
also, remember that, unlike classes, namespaces can divided multiple blocks.
you can reorganize code shown below:
// define command::s_command first. namespace command { struct s_command { int onplayercommandreceived; int onplayercommandperformed; }; } namespace amxe { void register(amx *amx); void release(amx *amx); struct s_amxe { command::s_command command; }; extern std::unordered_map<amx*, s_amxe*> *list; } // define rest of command namespace namespace command { extern dword onplayercommandtext_addr; void initialize(); void registerallfromamx(amx* amx, amxe::s_amxe* amxdata); cell command_addaltnamed_n(amx *amx, cell *params); }
