Implement a helper function which, given an input string: - copies it verbatim if it contains at least one path separator, - prepends the named plugin installation directory to it otherwise. This function will allow configuration parsing code to conveniently determine the full path to a plugin module given either a path or a filename. While other, simpler ways exist for making sure filenames passed to dlopen() cause the latter to look for shared objects in a specific directory, they are very platform-specific. Using full paths is thus likely the most portable and reliable solution. Also added unit tests for ns_plugin_expandpath() to ensure it behaves as expected for absolute paths, relative paths, and filenames, for various target buffer sizes. (Note: plugins share a directory with named on Windows; there is no default plugin path. Therefore the source path is copied to the destination path with no modification.) |
