Member Function Documentation

error()

const char * uvw::shared_lib::error ( ) const

noexcept

Returns the last error message, if any.

Returns

The last error message, if any.

operator bool()

uvw::shared_lib::operator bool ( ) const

explicitnoexcept

Checks if the library has been correctly opened.

Returns

True if the library is opened, false otherwise.

sym()

template<typename F >

F * uvw::shared_lib::sym ( const std::string &  name )

inline

Retrieves a data pointer from a dynamic library.

F shall be a valid function type (as an example, void(int)).
It is legal for a symbol to map to nullptr.

Parameters

name	The symbol to be retrieved.

Returns

A valid function pointer in case of success, nullptr otherwise.
