API

int uv_dlopen(const char *filename, uv_lib_t *lib)

Opens a shared library. The filename is in utf-8. Returns 0 on success and -1 on error. Call uv_dlerror() to get the error message.

void uv_dlclose(uv_lib_t *lib)

Close the shared library.

int uv_dlsym(uv_lib_t *lib, const char *name, void **ptr)

Retrieves a data pointer from a dynamic library. It is legal for a symbol to map to NULL. Returns 0 on success and -1 if the symbol was not found.

const char *uv_dlerror(const uv_lib_t *lib)

Returns the last uv_dlopen() or uv_dlsym() error message.
