/*
* Function: val_gethostbyname
*
* Purpose: A validating DNSSEC-aware version of the gethostbyname function.
* This function supports only IPv4 addresses.
*
* Parameters:
* ctx -- The validation context. Can be NULL for default value.
* name -- The domain name or IPv4 address in dotted-decimal format.
* val_status -- A pointer to a val_status_t variable to hold the
* returned validation-status value. This parameter
* must not be NULL.
* If successful, *val_status will contain a success
* code. If there is a failure, *val_status will contain
* the validator error code. To test whether the returned
* error code represents a trustworthy status, the caller
* can use the val_istrusted() function.
*
* Return value:
* Returns the entry from the host database or DNS for host on success.
* Returns NULL on failure.
*
* See also: val_gethostbyname_r(), val_gethostbyname2, val_istrusted()
