dlsym(3) Library Functions Manual dlsym(3) NAME top dlsym, dlvsym - obtain address of a symbol in a shared object or executable LIBRARY top Dynamic linking library (libdl, -ldl) SYNOPSIS top #include <dlfcn.h> void *dlsym(void *restrict handle, const char *restrict symbol); #define _GNU_SOURCE #include <dlfcn.h> void *dlvsym(void *restrict handle, const char …

dlsym() The function dlsym() takes a "handle" of a dynamic library returned by dlopen() and the null-terminated symbol name, returning the address where that symbol is loaded into memory. dlsym(3) - Linux man page Name. dladdr, dlclose, dlerror, dlopen, dlsym, dlvsym - programming interface to dynamic linking loader

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.

4.3. 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:

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 ...

DESCRIPTION. The dlsym() function shall obtain the address of a symbol defined within an object made accessible through a dlopen() call.The handle argument is the value returned from a call to dlopen() (and which has not since been released via a call to dlclose()), and name is the symbol's name as a character string. The dlsym() function shall search for the named symbol in all …

The dlsym() function shall obtain the address of a symbol (a function identifier or a data object identifier) defined in the symbol table identified by the handle argument. The handle argument is a symbol table handle returned from a call to dlopen () (and which has not since been released by a call to dlclose ()), and name is the symbol's name ...

The dlsym() function shall obtain the address of a symbol (a function identifier or a data object identifier) defined in the symbol table identified by the handle argument. The handle argument …
