Detailed Description

Abstraction for a DLL (Dynamically Linked Library) that is linked in to the running program.

Definition at line 13 of file ckdll.h.

CkDll::CkDll ( const char * sharedLibraryName )

Open this DLL and link it into this program.

Definition at line 33 of file ckdll.C.

References handle.

CkDll::~CkDll ( )

Remove this DLL from the program.

This invalidates any pointers created with lookup-- any references to this dll's function pointers will crash the program (or worse).

Definition at line 39 of file ckdll.C.

int CkDll::valid ( void ) const [inline]

Return true if the link-in was successful.

Definition at line 22 of file ckdll.h.

References handle.

void * CkDll::lookup ( const char * symbolName )

Resolve this symbol in the DLL, and return its pointer.

If the symbol is a function, you can cast this to a function pointer and call it. If that symbol name is not found, returns NULL.

Definition at line 36 of file ckdll.C.

const char * CkDll::extension = 0 [static]

Filename extension used by DLLs on this machine (e.g., ".dll" or ".so").
