使用如下代码,可检测Cocos2d-x中使用的libcurl库的版本信息 #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)#include ../cocos2d/external/curl/include/ios/curl/curl.h#endif#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)#include ../cocos2d/external/
使用如下代码,可检测Cocos2d-x中使用的libcurl库的版本信息
#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS) #include "../cocos2d/external/curl/include/ios/curl/curl.h" #endif #if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) #include "../cocos2d/external/curl/include/android/curl/curl.h" #endif int getVersion() { CURLcode return_code; return_code = curl_global_init(CURL_GLOBAL_ALL); if(CURLE_OK != return_code) { log("init libcurl failed"); return -1; } log("curl_version=%s",curl_version()); curl_version_info_data *p = curl_version_info(CURLVERSION_NOW); log("curl_version_info_data = %u",p->version_num); curl_global_cleanup(); return 0; }
CURL_GLOBAL_ALL Initialize everything possible. This sets all known bits except CURL_GLOBAL_ACK_EINTR.
CURL_GLOBAL_SSL Initialize SSL
CURL_GLOBAL_WIN32 Initialize the Win32 socket libraries.
CURL_GLOBAL_NOTHING Initialise nothing extra. This sets no bit.
CURL_GLOBAL_DEFAULT A sensible default. It will init both SSL and Win32. Right now, this equals the functionality of the CURL_GLOBAL_ALL mask.
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. (Added in 7.30.0)
2、curl_version_info_data结构体typedef struct { CURLversion age; /* age of the returned struct */ const char *version; /* LIBCURL_VERSION */ unsigned int version_num; /* LIBCURL_VERSION_NUM */ const char *host; /* OS/host/cpu/machine when configured */ int features; /* bitmask, see defines below */ const char *ssl_version; /* human readable string */ long ssl_version_num; /* not used anymore, always 0 */ const char *libz_version; /* human readable string */ /* protocols is terminated by an entry with a NULL protoname */ const char * const *protocols; /* The fields below this were added in CURLVERSION_SECOND */ const char *ares; int ares_num; /* This field was added in CURLVERSION_THIRD */ const char *libidn; /* These field were added in CURLVERSION_FOURTH */ /* Same as '_libiconv_version' if built with HAVE_ICONV */ int iconv_ver_num; const char *libssh_version; /* human readable string */ } curl_version_info_data;3、curl_global_init初始化libcurl,CURL_GLOBAL_ALL会使libcurl初始化所有的子模块和一些默认的选项,这个一个比较好的默认值
4、curl_global_cleanup,释放资源,curl_global_init和curl_global_cleanup只能被调用一次。
