Subject: [PATCH 2/2] curl_global_init: accept the CURL_GLOBAL_ACK_EINTR flag
|
|
|
|
The flag can be used in pycurl-based applications where using the multi
|
|
interface would not be acceptable because of the performance lost caused
|
|
by implementing the select() loop in python.
|
|
|
|
Bug: http://curl.haxx.se/bug/view.cgi?id=1168
|
|
Downstream Bug: https://bugzilla.redhat.com/919127

.B CURL_GLOBAL_DEFAULT
|
|
A sensible default. It will init both SSL and Win32. Right now, this equals
|
|
the functionality of the \fBCURL_GLOBAL_ALL\fP mask.

|
|
+.B CURL_GLOBAL_ACK_EINTR
|
|
+When this flag is set, curl will acknowledge EINTR condition when connecting
|
|
+or when waiting for data. Otherwise, curl waits until full timeout elapses.
|
|
.SH RETURN VALUE
|
|
If this function returns non-zero, something went wrong and you cannot use the
|
|
other curl functions.
