Function Documentation

const char* apr_dso_error (  apr_dso_handle_t *  dso, char *  buf, apr_size_t  bufsize )

Report more information when a DSO function fails. Parameters: dso  The dso handle that has been opened buf  Location to store the dso error bufsize  The size of the provided buffer

apr_status_t apr_dso_load (  apr_dso_handle_t **  res_handle, const char *  path, apr_pool_t *  ctx )

Load a DSO library. Parameters: res_handle  Location to store new handle for the DSO. path  Path to the DSO library ctx  Pool to use. Bug: We aught to provide an alternative to RTLD_GLOBAL, which is the only supported method of loading DSOs today.

apr_status_t apr_dso_sym (  apr_dso_handle_sym_t *  ressym, apr_dso_handle_t *  handle, const char *  symname )

Load a symbol from a DSO handle. Parameters: ressym  Location to store the loaded symbol handle  handle to load the symbol from. symname  Name of the symbol to load.

apr_status_t apr_dso_unload (  apr_dso_handle_t *  handle  )

Close a DSO library. Parameters: handle  handle to close.
