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);
