API GetNumGuildMembers

__NOTOC__
Returns the number of total and online guild members.
 numTotalGuildMembers, numOnlineGuildMembers, numOnlineAndMobileMembers = GetNumGuildMembers()
==Parameters==
===Arguments===
===Returns===
:;numTotalGuildMembers: - Total number of players in the Guild, or 0 if not in a guild.
:;numOnlineGuildMembers: - Number of players currently online in Guild, or 0 if not in a guild.
:;numOnlineAndMobileMembers: - Number of players currently online in Guild (includes players online through the mobile application), or 0 if not in a guild.
==Example==
 local numTotal, numOnline, numOnlineAndMobile = GetNumGuildMembers();
 DEFAULT_CHAT_FRAME:AddMessage(numTotal .. " guild members: " .. numOnline .. " online, " .. (numTotal - numOnline) .. " offline, " .. (numOnlineAndMobile - numOnline) .. " on mobile.");
===Result===
Displays the number of people online, offline, on mobile, and the total headcount of your guild in the default chat frame.
==Details==
You may need to call GuildRoster() first in order to obtain correct data. May return wrong values immediately after quitting a guild. Maximum returned value is 500.
There is another problem with the return values as they depend on SetGuildRosterShowOffline() setting. A simple program like
 DEFAULT_CHAT_FRAME:AddMessage("Firing SetGuildRosterShowOffline(false)");
 SetGuildRosterShowOffline(false)
 DEFAULT_CHAT_FRAME:AddMessage("GetNumGuildMembers(): "..tostring(GetNumGuildMembers()));
 DEFAULT_CHAT_FRAME:AddMessage("Firing SetGuildRosterShowOffline(true)");
 SetGuildRosterShowOffline(true)
 DEFAULT_CHAT_FRAME:AddMessage("GetNumGuildMembers(): "..tostring(GetNumGuildMembers()));
will show the difference.
Take care, if your function called by event handling wants to set the show offline status via SetGuildRosterShowOffline(). This may cause, due to guild roster updates, a loop, where a user that has opened the guild panel can't switch the status anymore, even if you reset the original status in your function.
This is because SetGuildRosterShowOffline() fires an event if changed.
