DESCRIPTIONThe <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.
