NAME

curl_version - returns the libcurl version string  

SYNOPSIS

#include <curl/curl.h>

char *curl_version();

 

DESCRIPTION

Returns a human readable string with the version number of libcurl and some of its important components (like OpenSSL version).

For MultiSSL builds the string contains all SSL backend names and the inactive backend names are in parentheses. For example "(OpenSSL/3.0.8) Schannel" or "OpenSSL/3.0.8 (Schannel)".

We recommend using curl_version_info(3) instead.  

PROTOCOLS

This functionality affects all supported protocols  

EXAMPLE

int main(void)
{
  printf("libcurl version %s\n", curl_version());
}

 

AVAILABILITY

Added in curl 7.1  

RETURN VALUE

A pointer to a null-terminated string. The string resides in a statically allocated buffer and must not be freed by the caller.
