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);
