dlfcn.h - dynamic linking
The <dlfcn.h> header shall define at least the following symbolic constants for use in the construction of a dlopen() mode argument:
- Relocations are performed at an implementation-defined time.
- 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);
XSH dlclose, dlerror, dlopen, dlsym
First released in Issue 5.
The restrict keyword is added to the prototype for dlsym().
The <dlfcn.h> header is moved from the XSI option to the Base.
This reference page is clarified with respect to macros and symbolic constants.
