The SharedLibrary class dynamically loads shared libraries at run-time.

◆ Flags
| Enumerator |
|---|
| SHLIB_GLOBAL | On platforms that use dlopen(), use RTLD_GLOBAL. This is the default if no flags are given.
This flag is ignored on platforms that do not use dlopen().
|
| SHLIB_LOCAL | On platforms that use dlopen(), use RTLD_LOCAL instead of RTLD_GLOBAL. Note that if this flag is specified, RTTI (including dynamic_cast and throw) will
not work for types defined in the shared library with GCC and possibly other
compilers as well. See http://gcc.gnu.org/faq.html#dso for more information.
This flag is ignored on platforms that do not use dlopen().

◆ getSymbol()
| void * BT::SharedLibrary::getSymbol |

|
Returns the address of the symbol with the given name. For functions, this is the entry point of the function. Throws a NotFoundException if the symbol does not exist.

◆ hasSymbol()

Returns true iff the loaded library contains a symbol with the given name.

| |
Loads a shared library from the given path, using the given flags. See the Flags enumeration for valid values. Throws a LibraryAlreadyLoadedException if a library has already been loaded. Throws a LibraryLoadException if the library cannot be loaded.

◆ operator=()
◆ prefix()
| std::string BT::SharedLibrary::prefix |
( |
| ) |
|
|
static |
Returns the platform-specific filename prefix for shared libraries. Most platforms would return "lib" as prefix, while on Cygwin, the "cyg" prefix will be returned.
Definition at line 65 of file shared_library_UNIX.cpp.
◆ suffix()
| std::string BT::SharedLibrary::suffix |
( |
| ) |
|
|
static |
Returns the platform-specific filename suffix for shared libraries (including the period). In debug mode, the suffix also includes a "d" to specify the debug version of a library.
