[PATCH v3 2/4] http: make curl callbacks match contracts from curl header

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan McGee <dpmcgee@xxxxxxxxx>

Yes, these don't match perfectly with the void* first parameter of the
fread/fwrite in the standard library, but they do match the curl
expected method signature. This is needed when a refactor passes a
curl_write_callback around, which would otherwise give incorrect
parameter warnings.
