Public Member Functions

 OSD_SharedLibrary ()
 Creates a SharedLibrary object with name NULL.

 OSD_SharedLibrary (const Standard_CString aFilename)
 Creates a SharedLibrary object with name aFilename.

void SetName (const Standard_CString aName)
 Sets a name associated to the shared object.

Standard_CString Name () const
 Returns the name associated to the shared object.

Standard_Boolean DlOpen (const OSD_LoadMode Mode)
 The DlOpen method provides an interface to the
dynamic library loader to allow shared libraries
to be loaded and called at runtime. The DlOpen
function attempts to load Filename, in the address
space of the process, resolving symbols as appropriate.
Any libraries that Filename depends upon are also loaded.
If MODE is RTLD_LAZY, then the runtime loader
does symbol resolution only as needed.
Typically, this means that the first call to a function
in the newly loaded library will cause the resolution of
the address of that function to occur.
If Mode is RTLD_NOW, then the runtime loader must do all
symbol binding during the DlOpen call.
The DlOpen method returns a handle that is used by DlSym
or DlClose.
If there is an error, Standard_False is returned,
Standard_True otherwise.
If a NULL Filename is specified, DlOpen returns a handle
for the main executable, which allows access to dynamic
symbols in the running program.

OSD_Function DlSymb (const Standard_CString Name) const
 The dlsym function returns the address of the
symbol name found in the shared library.
If the symbol is not found, a NULL pointer is
returned.

void DlClose () const
 Deallocates the address space for the library
corresponding to the shared object.
If any user function continues to call a symbol
resolved in the address space of a library
that has been since been deallocated by DlClose,
the results are undefined.

Standard_CString DlError () const
 The dlerror function returns a string describing
the last error that occurred from
a call to DlOpen, DlClose or DlSym.

void Destroy ()
 Frees memory allocated.
