Describes dynamic linking.
#include <dlfcn.h>
The <dlfcn.h> header defines at least the following macros for use in the construction of a dlopen mode argument:
| RTLD_LAZY | Relocations are performed at an implementation-dependent 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 header <dlfcn.h> declares the following functions, which may also be defined as macros:
void *dlopen(const char *, int); void *dlsym(void *, const char *); int dlclose(void *); char *dlerror(void);
The dlopen, dlclose, dlsym, dlerror subroutines.
