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 pro-
      vided.
 
             int    dlclose(void *);
             char  *dlerror(void);
             void  *dlopen(const char *, int);
             void  *dlsym(void *restrict, const char *restrict);
