- Relocations are performed when the object is loaded.
- All symbols are available for relocation processing of other modules.
- 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);
