NAME
       dlfcn.h - dynamic linking

SYNOPSIS
       #include <dlfcn.h>

DESCRIPTION
       The  <dlfcn.h>  header  shall define at least the following macros for
       use in the construction of a dlopen() mode argument:

       RTLD_LAZY
	      Relocations are performed at an implementation-defined time.

       RTLD_NOW
	      Relocations are performed when the object is loaded.

       RTLD_GLOBAL
	      All symbols are available for relocation	processing  of	other
	      modules.

       RTLD_LOCAL
	      All symbols are not made available for relocation processing by
	      other modules.


       The following shall be declared as functions and may also  be  defined
       as macros. Function prototypes shall be provided.


	      int    dlclose(void *);
	      char  *dlerror(void);
	      void  *dlopen(const char *, int);
	      void  *dlsym(void *restrict, const char *restrict);
