Sorry, you're right, the #if silently fails because CURL_SSLVERSION_xxx is an
enum not a #define symbol.
Unfortunately, I can't think of a way to do this that doesn't feel a bit
hackish, but the following does work:
#include <curl/curl.h>
// These may not exist in some versions of the enum.
#define CURL_SSLVERSION_TLSv1_0 (CURL_SSLVERSION_SSLv3 + 1)
#define CURL_SSLVERSION_TLSv1_1 (CURL_SSLVERSION_SSLv3 + 2)
#define CURL_SSLVERSION_TLSv1_2 (CURL_SSLVERSION_SSLv3 + 3)
static struct {
const char * name;
long ssl_version;
} Sslversions [] = {
{"SSLv2", CURL_SSLVERSION_SSLv2},
{"SSLv3", CURL_SSLVERSION_SSLv3},
{"TLSv1", CURL_SSLVERSION_TLSv1},
{CURL_SSLVERSION_TLSv1_0<CURL_SSLVERSION_LAST?"Tlsv1.0":NULL,
CURL_SSLVERSION_TLSv1_0},
{CURL_SSLVERSION_TLSv1_1<CURL_SSLVERSION_LAST?"Tlsv1.1":NULL,
CURL_SSLVERSION_TLSv1_1},
{CURL_SSLVERSION_TLSv1_2<CURL_SSLVERSION_LAST?"Tlsv1.2":NULL,
CURL_SSLVERSION_TLSv1_2},
{NULL}
};
int main(void) {
int i;
for(i = 0; Sslversions[i].name; i++) {
printf("Name: %s, Const: %d\n", Sslversions[i].name,
Sslversions[i].ssl_version);
}
}
