-.TH GAI.CONF 5 2013-02-13 "Linux" "Linux Programmer's Manual"
-.SH NAME
-gai.conf \- getaddrinfo(3) configuration file
-.SH DESCRIPTION
-A call to
-.BR getaddrinfo (3)
-might return multiple answers.
-According to RFC\ 3484 these answers must be sorted so that
-the answer with the highest success rate is first in the list.
-The RFC provides an algorithm for the sorting.
-The static rules are not always adequate, though.
-For this reason,
-the RFC also requires that system administrators should have the possibility
-to dynamically change the sorting.
-For the glibc implementation, this can be achieved with the
-.IR /etc/gai.conf
-file.
-.PP
-Each line in the configuration file consists of a keyword and its parameters.
-White spaces in any place are ignored.
-Lines starting with \(aq#\(aq are comments and are ignored.
-.PP
-The keywords currently recognized are:
-.TP
-\fBlabel\fR \fInetmask\fR \fIprecedence\fR
-The value is added to the label table used in the RFC\ 3484 sorting.
-If any \fBlabel\fR definition is present in the configuration file
-is present, the default table is not used.
-All the label definitions
-of the default table which are to be maintained have to be duplicated.
-Following the keyword,
-the line has to contain a network mask and a label value.
-.TP
-\fBprecedence\fR \fInetmask\fR \fIprecedence\fR
-This keyword is similar to \fBlabel\fR, but instead the value is added
-to the precedence table as specified in RFC\ 3484.
-Once again, the
-presence of a single \fBprecedence\fR line in the configuration file
-causes the default table to not be used.
-.TP
-\fBreload\fR <\fByes\fR|\fBno\fR>
-This keyword controls whether a process checks whether the configuration
-file has been changed since the last time it was read.
-If the value is
-"\fByes\fR", the file is reread.
-This might cause problems in multithreaded
-applications and is generally a bad idea.
-The default is "\fBno\fR".
-.TP
-\fBscopev4\fR \fImask\fR \fIvalue\fR
-Add another rule to the RFC\ 3484 scope table for IPv4 address.
-By default, the scope IDs described in section 3.2 in RFC\ 3438 are used.
-Changing these defaults should hardly ever be necessary.
-.SH FILES
-\fI/etc/gai.conf\fR
-.SH EXAMPLE
-The default table according to RFC\ 3484 would be specified with the
-following configuration file:
-
-.nf
-label ::1/128 0
-label ::/0 1
-label 2002::/16 2
-label ::/96 3
-label ::ffff:0:0/96 4
-precedence ::1/128 50
-precedence ::/0 40
-precedence 2002::/16 30
-precedence ::/96 20
-precedence ::ffff:0:0/96 10
