Instead of sleeping unconditionally for a 50ms, when no data can be read from the http connection(s), use curl_multi_fdset to obtain the actual file descriptors of the open connections and use them in the select call. This way, the 50ms sleep is interrupted when new data arrives. Signed-off-by: Mika Fischer <redacted> --- http.c | 6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-)
