Socket6 also provides these functions, in a form taking and returning flat lists of values. .PP This module wraps the functions provided by \f(CW\*(C`Socket::GetAddrInfo\*(C'\fR to provide them in an identical \s-1API\s0 to \f(CW\*(C`Socket6\*(C'\fR. It is intended to stand as a utility for existing code written for the \f(CW\*(C`Socket6\*(C'\fR \s-1API\s0 to use these functions instead. .SH "FUNCTIONS" .IX Header "FUNCTIONS" .ie n .SS "@res = getaddrinfo( $host, $service, $family, $socktype, $protocol, $flags )" .el .SS "\f(CW@res\fP = getaddrinfo( \f(CW$host\fP, \f(CW$service\fP, \f(CW$family\fP, \f(CW$socktype\fP, \f(CW$protocol\fP, \f(CW$flags\fP )" .IX Subsection "@res = getaddrinfo( $host, $service, $family, $socktype, $protocol, $flags )" This version of the \s-1API\s0 takes the hints values as separate ordered parameters. Unspecified parameters should be passed as \f(CW0\fR. .PP If successful, this function returns a flat list of values, five for each returned address structure. Each group of five elements will contain, in order, the \f(CW\*(C`family\*(C'\fR, \f(CW\*(C`socktype\*(C'\fR, \f(CW\*(C`protocol\*(C'\fR, \f(CW\*(C`addr\*(C'\fR and \f(CW\*(C`canonname\*(C'\fR values of the address structure. .PP If unsuccessful, it will return a single value, containing the string error message. To remain compatible with the \f(CW\*(C`Socket6\*(C'\fR interface, this value does not have the error integer part. .ie n .SS "( $host, $service ) = getnameinfo( $addr, $flags )" .el .SS "( \f(CW$host\fP, \f(CW$service\fP ) = getnameinfo( \f(CW$addr\fP, \f(CW$flags\fP )" .IX Subsection "( $host, $service ) = getnameinfo( $addr, $flags )" This version of the \s-1API\s0 returns only the host name and service name, if successfully resolved. On error, it will return an empty list. To remain compatible with the \f(CW\*(C`Socket6\*(C'\fR interface, no error information will be supplied. .SH "AUTHOR" .IX Header "AUTHOR" Paul Evans
