Import

External linkage attribute for public data located in DLL's

Syntax
	KeyPgExternExtern Import symbolname[( subscripts)] [ KeyPgAliasAlias "aliasname"] [ KeyPgAsAs 
	DataTypeDataType] [, ...]

Description
	Is used only (with the KeyPgExternExtern keyword) in external modules to access 
	global variables from Win32 DLLs: the variable names will be added to 
	the dynamic library import list so that their addresses can be fixed at 
	run-time.
	This is due to the level of indirection on any such access: an implicit 
	pointer dereference.

Example

	/* mydll.c :
		compile With
		  gcc -Shared -Wl,--strip-all -o mydll.dll mydll.c
	*/
	__declspec( dllexport ) Int MyDll_Data = 0x1234;

	/'  import.bas :
		Compile with
		  fbc import.bas
	'/
	#inclib "mydll"

	Extern Import MyDll_Data Alias "MyDll_Data" As Integer

	Print "&h" + Hex( MyDll_Data )

	' Output:
	' &h1234
