In another header file define an extern variable like this:
<MyVariableType> <MyVariable>
and in your files include:
extern <MyVariableType> <MyVariable>
A variable declared with the extern storage-class specifier is a reference to a variable with the same name defined at the external level in any of the source files of the program. The internal extern declaration is used to make the external-level variable definition visible within the block. Unless otherwise declared at the external level, a variable declared with the extern keyword is visible only in the block in which it is declared.
<MyVariableType> <MyVariable>
