steam_get_persona_name();
Returns: String
You can use this function to return the user name of the user
currently logged into the Steam client. This is the visible screen
name and not the unique user id (this can be found
using the function steam_get_user_steam_id).
if steam_initialised()
{
global.p_name = steam_get_persona_name();
}
The above code will set a global variable to current users screen name if the Steam client API is correctly initialised.
