38 * a_babel_convert modifies data in a trw layer using gpsbabel filters. This routine is synchronous;
39 * that is, it will block the calling program until the conversion is done. To avoid blocking, call
40 * this routine from a worker thread. The arguments are as follows:
42 * vt The TRW layer to modify. All data will be deleted, and replaced by what gpsbabel outputs.
44 * babelargs A string containing gpsbabel command line filter options. No file types or names should
47 * cb A callback function, called with the following status codes:
48 * BABEL_DIAG_OUTPUT: a line of diagnostic output is available. The pointer is to a
49 * NUL-terminated line of diagnostic output from gpsbabel.
50 * BABEL_DIAG_DONE: gpsbabel finished,
51 * or NULL if no callback is needed.
