Yu Qing created TS-2407:
---------------------------
Summary: should add API TSUrlStringGetBuf in ts.h
Key: TS-2407
URL: https://issues.apache.org/jira/browse/TS-2407
Project: Traffic Server
Issue Type: Improvement
Components: HTTP
Reporter: Yu Qing
the existing API TSUrlStringGet call ats_malloc to malloc buffer for the url
string. the caller should call ats_free to free the buffer. the API prototype
is:
tsapi char* TSUrlStringGet(TSMBuffer bufp, TSMLoc offset, int* length);
call this API is expensive because dynamic memory alloc and free.
we wish the buffer can be passed in. the new API prototype is:
tsapi char* TSUrlStringGetBuf(TSMBuffer bufp, TSMLoc offset, char *buff, int
buf_size, int* length);
the implements as:
char *
TSUrlStringGetBuf(TSMBuffer bufp, TSMLoc obj, char *buff, int buf_size, int*
length)
{
sdk_assert(sdk_sanity_check_mbuffer(bufp) == TS_SUCCESS);
sdk_assert(sdk_sanity_check_url_handle(obj) == TS_SUCCESS);
sdk_assert(sdk_sanity_check_null_ptr((void*)buff) == TS_SUCCESS);
sdk_assert(sdk_sanity_check_null_ptr((void*)length) == TS_SUCCESS);
URLImpl *url_impl = (URLImpl *) obj;
return url_string_get_buf(url_impl, buff, buf_size, length);
}
