General description

The endhostent() function closes the local host tables, which contains information about known hosts.

You can use the X_SITE environment variable to specify different local host tables and override those supplied by the z/OS global resolver during initialization. For more information on these local host tables or the environment variables, see z/OS V2R1.0 Communications Server: IP Configuration Guide.

Special behavior for C++: To use this function with C++, you must use the _XOPEN_SOURCE_EXTENDED 1 feature test macro.
