NAME

curl_share_init - Create a shared object

SYNOPSIS

#include <curl/curl.h>

CURLSH *curl_share_init();

DESCRIPTION

This function returns a pointer to a CURLSH handle to be used as input to all the other share-functions, sometimes referred to as a share handle in some places in the documentation. This init call MUST have a corresponding call to curl_share_cleanup(3) when all operations using the share are complete.

This share handle is what you pass to curl using the CURLOPT_SHARE(3) option with curl_easy_setopt(3), to make that specific curl handle use the data in this share.

EXAMPLE

int main(void)
{
  CURLSHcode sh;
  CURLSH *share = curl_share_init();
  sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT);
  if(sh)
    printf("Error: %s\n", curl_share_strerror(sh));
}

AVAILABILITY

Added in 7.10

RETURN VALUE

If this function returns NULL, something went wrong (out of memory, etc.) and therefore the share object was not created.
