Detailed Description

Shared library loader.

A class that can be used to dynamically load shared libraries to resolve symbols from it. The example below shows how to retrieve the address of the cos function in the math library:

SharedLib shl("libm.so");
double (*cosine)(double);
cosine = shl["cos"];
(*cosine)(2.0);
