Notes

• The HOSTENT structure area is allocated by the system at the CA IDMS task level, and freed at task termination. It is reused by subsequent calls to a DNS function: GETHOSTBYADDR or GETHOSTBYNAME.
• For more information about the HOSTENT structure, see Socket Structure Descriptions.

z/VM systems: The DNS socket functions are supported by CA IDMS's internal DNS resolver. For information about configuring the DNS resolver, see the TCP/IP Considerations section of the CA IDMS System Operations Guide.

z/VSE systems: The DNS socket functions can be supported by CA IDMS's internal DNS resolver. If the socket functions are supported by CA IDMS, see the TCP/IP Considerations section of CA IDMS System Operations Guide for information about configuring the DNS resolver. If the socket functions are supported by Barnard Software Inc. or Connectivity Systems Inc., see the appropriate TCP/IP stack documentation for configuring DNS support.
