GETHOSTBYADDR returns the HOSTENT structure shown in Figure 1. Figure 1. HOSTENT structure
that is returned by the GETHOSTBYADDR call
GETHOSTBYADDR returns the HOSTENT structure shown in figure Figure 1. The HOSTENT structure is a tasks's serially reusable storage area. It should not be used or referenced between MVS™ tasks. The storage is freed when the task terminates. The assembler mapping of the structure is defined in macro EZBREHST, which is installed in the data set specified on your SMP/E DDDEF for MACLIB. The EZBREHST assembler macro is stored in the SYS1.MACLIB library. The macro defines the resolver hostent (host entry), address information (addrinfo) mappings, and services return codes. This structure contains:
The HOSTENT structure uses indirect addressing to return a variable number of alias names and IP addresses. If you are coding in PL/I or assembly language, this structure can be processed in a relatively straight-forward manner. If you are coding in COBOL, this structure might be difficult to interpret. You can use the subroutine EZACIC08 to simplify interpretation of the information returned by the GETHOSTBYADDR and GETHOSTBYNAME calls. For more information about EZACIC08, see EZACIC08. |
