| .SH NAME |
| curl_easy_init - Start a libcurl easy session |
| .SH SYNOPSIS |
| .B #include <curl/curl.h> |
| |
| .BI "CURL *curl_easy_init( );" |
| .SH DESCRIPTION |
| This function must be the first function to call, and it returns a CURL easy |
| handle that you must use as input to other functions in the easy |
| interface. This call \fBMUST\fP have a corresponding call to |
| \fIcurl_easy_cleanup(3)\fP when the operation is complete. |
| |
| If you did not already call \fIcurl_global_init(3)\fP, \fIcurl_easy_init(3)\fP |
| does it automatically. This may be lethal in multi-threaded cases, since |
| \fIcurl_global_init(3)\fP is not thread-safe, and it may result in resource |
| problems because there is no corresponding cleanup. |
| |
| You are strongly advised to not allow this automatic behaviour, by calling |
| \fIcurl_global_init(3)\fP yourself properly. See the description in |
| \fBlibcurl\fP(3) of global environment requirements for details of how to use |
| this function. |
| .SH RETURN VALUE |
| If this function returns NULL, something went wrong and you cannot use the |
| other curl functions. |
| .SH EXAMPLE |
| .nf |
| CURL *curl = curl_easy_init(); |
| if(curl) { |
| CURLcode res; |
| curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); |
| res = curl_easy_perform(curl); |
| curl_easy_cleanup(curl); |
| } |
