An error is thrown if this was used previously.

An error is thrown if this was used previously.

The input sockfd is used with [[Sockets_services#DuplicateSocket|DuplicateSocket]], with the output sockfd from that being written into state. If the field which would be used for the input u64 (PID set by [[#CreateContext]]) is zero however, it instead uses the input sockfd directly and returns -1 for the sockfd. An error is thrown if DuplicateSocket fails. When DuplicateSocket is successful, the input sockfd is returned as the output sockfd, however if [[#OptionType|DoNotCloseSocket]] is set it will instead return -1 for the sockfd.

internal_sockfd = output from [[Sockets_services#DuplicateSocket|DuplicateSocket]], with the input sockfd. If the field which would be used for the input u64 (PID set by [[#CreateContext]]) is zero however, it instead uses internal_sockfd=input_sockfd directly without DuplicateSocket and later returns -1 for the sockfd. An error is thrown if DuplicateSocket fails. The input sockfd is later returned as the output sockfd, however if [[#OptionType|DoNotCloseSocket]] is set it will instead return -1 for the sockfd. Then [[Sockets_services#GetPeerName|GetPeerName]] is used with internal_sockfd, throwing an error if this fails. internal_sockfd is used for state initialization, and the input_sockfd is written into state.

Immediately prior to closing the [[#ISslConnection]] object, sdknso will close the sockfd which was returned by this cmd if it is not negative.
