38This is the automatically generated usage text for ntpsnmpd.
39
40The text printed is the same whether selected with the @code{help} option
41(@option{--help}) or the @code{more-help} option (@option{--more-help}).  @code{more-help} will print
42the usage text by passing it through a pager program.
43@code{more-help} is disabled on platforms without a working
44@code{fork(2)} function.  The @code{PAGER} environment variable is
45used to select the program, defaulting to @file{more}.  Both will exit
46with a status code of 0.

64Options are specified by doubled hyphens and their name or by a single
65hyphen and the flag character.
66
67
68
69The following option preset mechanisms are supported:
70 - reading file $HOME/.ntprc
71 - reading file ./.ntprc
72 - examining environment variables named NTPSNMPD_*

80@cindex ntpsnmpd-agentxsocket
81
82This is the ``the socket address ntpsnmpd uses to connect to net-snmpd'' option.
83This option takes a string argument.
84[<transport-specifier>:]<transport-address>
85The default "agent X socket" is the Unix Domain socket
86@file{unix:/var/agentx/master}.
87Another common alternative is @file{tcp:localhost:705}.

90@node ntpsnmpd config
91@subsection presetting/configuring ntpsnmpd
92
93Any option that is not marked as @i{not presettable} may be preset by
94loading values from configuration ("rc" or "ini") files, and values from environment variables named @code{NTPSNMPD} and @code{NTPSNMPD_<OPTION_NAME>}.  @code{<OPTION_NAME>} must be one of
95the options listed above in upper case and segmented with underscores.
96The @code{NTPSNMPD} variable will be tokenized and parsed like
97the command line.  The remaining variables are tested for existence and their
98values are treated like option arguments.
99
100
101@noindent
102@code{libopts} will search in 2 places for configuration files:
103@itemize @bullet
104@item
105$HOME
106@item
107$PWD
108@end itemize
109The environment variables @code{HOME}, and @code{PWD}
110are expanded and replaced when @file{ntpsnmpd} runs.
111For any of these that are plain files, they are simply processed.
112For any that are directories, then a file named @file{.ntprc} is searched for
113within that directory and processed.
114
115Configuration files may be in a wide variety of formats.
116The basic format is an option name followed by a value (argument) on the
117same line.  Values may be separated from the option name with a colon,
118equal sign or simply white space.  Values may be continued across multiple
119lines by escaping the newline with a backslash.
120
121Multiple programs may also share the same initialization file.
122Common options are collected at the top, followed by program specific
123segments.  The segments are separated by lines like:
124@example
125[NTPSNMPD]
126@end example
127@noindent
128or by
129@example
130<?program ntpsnmpd>
131@end example
132@noindent
133Do not mix these styles within one configuration file.
134
135Compound values and carefully constructed string values may also be
136specified using XML syntax:
137@example
138<option-name>
139   <sub-opt>...&lt;...&gt;...</sub-opt>
140</option-name>
141@end example
142@noindent
143yielding an @code{option-name.sub-opt} string value of
144@example
145"...<...>..."
146@end example
147@code{AutoOpts} does not track suboptions.  You simply note that it is a
148hierarchicly valued option.  @code{AutoOpts} does provide a means for searching
149the associated name/value pair list (see: optionFindValue).
150
151The command line options relating to configuration and/or usage help are:
152
153@subsubheading version (-)
154
155Print the program version to standard out, optionally with licensing
156information, then exit 0.  The optional argument specifies how much licensing
157detail to provide.  The default is to print just the version.  The licensing infomation may be selected with an option argument.
158Only the first letter of the argument is examined:
159
160@table @samp
161@item version
162Only print the version.  This is the default.
163@item copyright
164Name the copyright usage licensing terms.
165@item verbose
166Print the full copyright usage licensing terms.

169@node ntpsnmpd exit status

171
172One of the following exit values will be returned:
173@table @samp
174@item 0 (EXIT_SUCCESS)
175Successful program execution.
176@item 1 (EXIT_FAILURE)
177The operation failed or the command syntax was not valid.
178@item 66 (EX_NOINPUT)
179A specified configuration file could not be loaded.
180@item 70 (EX_SOFTWARE)
181libopts had an internal operational error.  Please report
182it to autogen-users@@lists.sourceforge.net.  Thank you.
