Function Documentation
◆ vlc_dlclose()
| int vlc_dlclose | ( | void * | ) |
Unloads a dynamic library.
This function unloads a previously opened dynamically linked library using a system dependent method.
- Parameters
-
handle handle of the library
- Return values
-
0 on success -1 on error (none are defined though)
◆ vlc_dlerror()
| char* vlc_dlerror | ( | void | ) |
Formats an error message for vlc_dlopen() or vlc_dlsym().
- Returns
- a heap-allocated nul-terminated error string, or NULL.
References strdup().
◆ vlc_dlopen()
| void* vlc_dlopen | ( | const char * | path, |
| bool | |||
| ) |
Loads a dynamically linked library.
- Parameters
-
path library file path lazy whether to resolve the symbols lazily
- Returns
- a module handle on success, or NULL on error.
References VLC_UNUSED.
◆ vlc_dlsym()
| void* vlc_dlsym | ( | void * | handle, |
| const char * | |||
| ) |
Looks up a symbol from a dynamically loaded library.
This function looks for a named symbol within a loaded library.
- Parameters
-
handle handle to the library name function name
- Returns
- the address of the symbol on success, or NULL on error
- Note
- If the symbol address is NULL, errors cannot be detected. However, normal symbols such as function or global variables cannot have NULL as their address.
