Usage notes. The named symbol can be either an exported data item or function. DLLs are enclave level resources. See z/OS XL C/C++ Programming Guide for more information about the use of DLLs in a multi-threaded environment.; C++ symbol names should be passed to dlsym() in mangled form; dlsym() does not perform any name mangling on behalf of the calling application.
4. Dynamically Loaded (DL) Libraries - Linux Documentation Project
4.3. dlsym() There's no point in loading a DL library if you can't use it. The main routine for using a DL library is dlsym(3), which looks up the value of a symbol in a given (opened) library. This function is defined as:
Ubuntu Manpage: dlsym, dlvsym - obtain address of a symbol in a …
The value of a symbol returned by dlsym() will never be NULL if the shared object is the result of normal compilation, since a global symbol is never placed at the NULL address. There are nevertheless cases where a lookup using dlsym() may return NULL as the value of a symbol. For example, the symbol value may be the result of a GNU indirect ...
