+
+A simple dlopen/dlsym implementation backed by host functions.
+

+
+Build toywasm with the following options to include the host functions.
+```
+TOYWASM_ENABLE_DYLD=ON
+TOYWASM_ENABLE_DYLD_DLFCN=ON
+```
+
+Also, enable them with the `--dyld-dlfcn` runtime option.
+```
+toywasm --dyld --dyld-dlfcn
+```
+or, via `dyld_options.enable_dlfcn` if you are using toywasm as a library.
