This is C, so no reference parameters. Following the existing TSAPI
conventions, I'd recommend
TSReturnCode TSRemapFromUrlGet(TSHttpTxn txnp, TSMBuffer bufp, TSMLoc
obj);
char * TSRemapFromUrlStringGet(TSHttpTxn txnp, int *length);
TSReturnCode TSRemapToUrlGet(TSHttpTxn txnp, TSMBuffer bufp, TSMLoc
obj);
char * TSRemapToUrlStringGet(TSHttpTxn txnp, int *length);
In the documentation, please be sure to specify which hooks these APIs may be
called from. Consider writing an example plugin that can be consumed by tests
and included in the documentation.
I'm a not that fazed by the StringGet() APIs proposed here, but we should
consider whether we want to continue this API pattern, or defer the
stringification to TSUrlStringGet().
