IupGetGlobal
Verifies an attributes value in the global environment.
Parameters/Return
char *IupGetGlobal(char *a); [in C] IupGetGlobal(a: string) -> value: string [in IupLua3] iup.GetGlobal(a: string) -> value: string [in IupLua5]a: name of the attribute.
This function returns the attributes value. If the attribute does not exist, NULL (nil in Lua) is returned.
Note
This functions return value is not necessarily the same one used by the application to define the attributes value.
The subsequent call to the IupGetGlobal function may change the contents of the previously returned pointer, as this is an internal IUP buffer. The user is in charge of storing the value before calling IupGetGlobal again. This pointer must not be freed either.
