TODO

.SH AVAILABILITY
|
|
-This option is OpenSSL-specific and does nothing if libcurl is built to use
|
|
-GnuTLS. NSS-powered libcurl provides the option only for backward
|
|
-compatibility.
|
|
+This option is supported by the OpenSSL, GnuTLS and PolarSSL backends. The NSS

|
+backend provides the option only for backward compatibility.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if TLS enabled, and CURLE_UNKNOWN_OPTION if not, or
|
|
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
