# tcpwrap_check

(no version information, might be only in CVS)

tcpwrap_check -- tcpwrap check

## Description

bool tcpwrap_check ( string daemon, string address [, string user [, bool nodns]])

This function consults /etc/hosts.allow and /etc/hosts.deny files to check if access to service daemon should be granted or denied for client with remote address address (and optional username user). address can be either IP address or domain name. user can be `NULL`.

If address looks like domain name then DNS is used to resolve it to IP address; set nodns to `TRUE` to avoid this.

For more details please consult hosts_access(3) man page.

This function returns `TRUE` if access should be granted, `FALSE` otherwise.
