-
-libdl.a
--------
-
-This is an emulation library to emulate the SunOS/System V.4 functions
-to access the runtime linker. The functions are emulated by using the
-AIX load() function and by reading the .loader section of the loaded
-module to find the exports. The to be loaded module should be linked as
-follows (if using AIX 3):
-
-	cc -o module.so -bM:SRE -bE:module.exp -e _nostart $(OBJS)
-
-For AIX 4:
-
-	cc -o module.so -bM:SRE -bE:module.exp -bnoentry $(OBJS)
-
-The module export file contains the symbols to be exported. Because
-this library uses the loader section, the final module.so file can be
-stripped. C++ users should build their shared objects using the script
-makeC++SharedLib (part of the IBM C++ compiler), this will make sure
-that constructors and destructors for static and global objects will be
-called upon loading and unloading the module.
-
-Usage
------
-
-void *dlopen(const char *path, int mode);
-
-This routine loads the module pointed to by path and reads its export
-table. If the path does not contain a '/' character, dlopen will search
-for the module using the LIBPATH environment variable. It returns an
-opaque handle to the module or NULL on error. The mode parameter can be
-either RTLD_LAZY (for lazy function binding) or RTLD_NOW for immediate
-function binding. The AIX implementation currently does treat RTLD_NOW
-the same as RTLD_LAZY. The flag RTLD_GLOBAL might be or'ed into the
-mode parameter to allow loaded modules to bind to global variables or
-functions in other loaded modules loaded by dlopen(). If RTLD_GLOBAL is
-not specified, only globals from the main part of the executable or
-shared libraries are used to look for undefined symbols in loaded
-modules.
-
-
-void *dlsym(void *handle, const char *symbol);
-
-This routine searches for the symbol in the module referred to by
-handle and returns its address. If the symbol could not be found, the
-function returns NULL. The return value must be casted to a proper
-function pointer before it can be used. SunOS/System V.4 allows handle
-to be a NULL pointer to refer to the module the call is made from, this
-is not implemented.
-
-int dlclose(void *handle);
-
-This routine unloads the module referred to by the handle and disposes
-of any local storage. this function returns -1 on failure.
-
-char *dlerror(void);
-
-This routine can be used to retrieve a text message describing the most
-recent error that occured on on of the above routines. This function
-returns NULL if there is no error information.
-
-Initialization and termination handlers
----------------------------------------
-
-The emulation provides for an initialization and a termination
-handler.  The dlfcn.h file contains a structure declaration named
-dl_info with following members:
-
-	void (*init)(void);
-	void (*fini)(void);
-
-The init function is called upon first referencing the library. The
-fini function is called at dlclose() time or when the process exits.
-The module should declare a variable named dl_info that contains this
-structure which must be exported.  These functions correspond to the
-documented _init() and _fini() functions of SunOS 4.x, but these are
-appearently not implemented in SunOS.  When using SunOS 5.0, these
-correspond to #pragma init and #pragma fini respectively. At the same
-time any static or global C++ object's constructors or destructors will
-be called.
-
-BUGS
-----
-
-Please note that there is currently a problem with implicitely loaded
-shared C++ libaries: if you refer to a shared C++ library from a loaded
-module that is not yet used by the main program, the dlopen() emulator
-does not notice this and does not call the static constructors for the
-implicitely loaded library. This can be easily demonstrated by
-referencing the C++ standard streams from a loaded module if the main
-program is a plain C program.
