_dyld_present returns non-zero if the dynamic linker is being used in the program and zero otherwise. If this returns zero this rest of these functions should not be called and most likely crash the program if called.
_dyld_image_count returns the current number of images mapped in by the dynamic link editor.
_dyld_get_image_header returns the mach header of the image indexed by image_index. If image_index is out of range NULL is returned.
_dyld_get_image_vmaddr_slide returns the virtural memory address slide amount of the image indexed by image_index. If image_index is out of range zero is returned.
_dyld_get_image_name returns the name of the image indexed by image_index. If image_index is out of range NULL is returned.
_dyld_lookup_and_bind looks up the symbol_name and binds it into the program. It indirectly returns the address and and a pointer to the module that defined the symbol.
_dyld_lookup_and_bind_fully looks up the symbol_name and binds it and all of its references into the program. It indirectly returns the address and and a pointer to the module that defined the symbol.
_dyld_bind_fully_image_containing_address fully binds the image containing the specified address. It returns TRUE if the address is contained in a loaded image and FALSE otherwise.
_dyld_launched_prebound returns TRUE if the program was launched using the prebound state and FALSE otherwise.
_dyld_func_lookup is passed a name, dyld_func_name, of a dynamic link editor function and returns the address of the function indirectly. It returns non-zero if the function is found and zero otherwise.
