NAME

Net::Curl::Share - Perl interface for curl_share_* functions

SYNOPSIS

 use Net::Curl::Share qw(:constants);
 my $share = Net::Curl::Share->new();
 $share->setopt( CURLSHOPT_SHARE, CURL_LOCK_DATA_COOKIE );
 $share->setopt( CURLSHOPT_SHARE, CURL_LOCK_DATA_DNS );
 $easy_one->setopt( CURLOPT_SHARE() => $share );
 $easy_two->setopt( CURLOPT_SHARE() => $share );

DESCRIPTION

This module wraps share handle from libcurl and all related functions and constants. It does not export by default anything, but constants can be exported upon request.

 use Net::Curl::Share qw(:constants);

CONSTRUCTOR

new( [BASE] )

Creates new Net::Curl::Share object. If BASE is specified it will be used as object base, otherwise an empty hash will be used. BASE must be a valid reference which has not been blessed already. It will not be used by the object.

 my $share = Net::Curl::Share->new( [qw(my very private data)] );

Calls curl_share_init(3) <https://curl.haxx.se/libcurl/c/curl_share_init.html>.

METHODS

setopt( OPTION, VALUE )

Set an option. OPTION is a numeric value, use one of CURLSHOPT_* constants. VALUE depends on whatever that option expects.

 $share->setopt( CURLSHOPT_SHARE, CURL_LOCK_DATA_COOKIE );

Calls curl_share_setopt(3) <https://curl.haxx.se/libcurl/c/curl_share_setopt.html>. Throws "Net::Curl::Share::Code" on error.

FUNCTIONS

None of those functions are exported, you must use fully qualified names.

strerror( [WHATEVER], CODE )

Return a string for error code CODE.

 my $message = Net::Curl::Share::strerror( CURLSHE_BAD_OPTION );

See curl_share_strerror(3) <https://curl.haxx.se/libcurl/c/curl_share_strerror.html> for more info.

CONSTANTS

CURLSHOPT_*: Values for setopt().
CURL_LOCK_ACCESS_*: Values passed to lock callbacks. Unused.
CURL_LOCK_DATA_*: Values passed to lock and unlock callbacks. Unused.
CURL_LOCK_DATA_COOKIE, CURL_LOCK_DATA_DNS: Values used to enable/disable shareing.

CALLBACKS

Reffer to libcurl documentation for more detailed info on each of those.

CURLSHOPT_LOCKFUNC ( CURLSHOPT_USERDATA ): Not supported. Locking is done internally.
CURLSHOPT_UNLOCKFUNC ( CURLSHOPT_USERDATA ): Not supported. (Un)Locking is done internally.

Net::Curl::Share setopt method on failure throws a Net::Curl::Share::Code error object. It has both numeric value and, when used as string, it calls strerror() function to display a nice message.
