curl_version_info - returns run-time libcurl version info
curl_version_info_data *curl_version_info( CURLversion type);
data = curl_version_info(CURLVERSION_NOW);
Applications should use this information to judge if things are possible to do or not, instead of using compile-time checks, as dynamic/DLL libraries can be changed independent of applications.
The curl_version_info_data struct looks like this
typedef struct {
CURLversion age; /* see description below */
/* when 'age' is 0 or higher, the members below also exist: */
const char *version; /* human readable string */
unsigned int version_num; /* numeric representation */
const char *host; /* human readable string */
int features; /* bitmask, see below */
char *ssl_version; /* human readable string */
long ssl_version_num; /* not used, always zero */
const char *libz_version; /* human readable string */
const char **protocols; /* list of protocols */
/* when 'age' is 1 or higher, the members below also exist: */
const char *ares; /* human readable string */
int ares_num; /* number */
/* when 'age' is 2 or higher, the member below also exists: */
const char *libidn; /* human readable string */
} curl_version_info_data;
age describes what age of this struct this is. The number depends on how new libcurl you're using. You are however guaranteed to get a struct that you have a matching struct for in the header, as you tell libcurl your "age" with the input argument.
version is just an ascii string for the libcurl version.
version_num is a 24 bit number created like this: <8 bits major number> | <8 bits minor number> | <8 bits patch number>. Version 7.9.8 is therefore returned as 0x070908.
host is an ascii string showing what host information that this libcurl was built for. As discovered by a configure script or set by the build environment.
features can have none, one or more bits set, and the currently defined bits are:
ssl_version_num is the numerical OpenSSL version value as defined by the OpenSSL project. If libcurl has no SSL support, this is 0.
libz_version is an ascii string (there is no numerical version). If libcurl has no libz support, this is NULL.
protocols is a pointer to an array of char * pointers, containing the names protocols that libcurl supports (using lowercase letters). The protocol names are the same as would be used in URLs. The array is terminated by a NULL entry.
