.SH DESCRIPTION
|
|
|
|
The
|
2014-06-11 10:29:16 +00:00
|
|
|
.BR iconv (3)
|
2014-06-11 08:09:47 +00:00
|
|
|
function internally uses
|
|
|
|
.I gconv
|
|
|
|
modules to convert to and from a character set.
|
|
|
|
A configuration file is used to determine the needed modules
|
|
|
|
for a conversion.
|
|
|
|
Loading and parsing such a configuration file would slow down
|
2014-06-11 10:29:16 +00:00
|
|
|
programs that use
|
|
|
|
.BR iconv (3),
|
|
|
|
so a caching mechanism is employed.
|
iconv.1, locale.1, localedef.1, memusage.1, memusagestat.1, mtrace.1, pldd.1, sprof.1, time.1, iconvconfig.8, ld.so.8, ldconfig.8, sln.8: Formatting fix: replace blank lines with .PP/.IP
Blank lines shouldn't generally appear in *roff source (other
than in code examples), since they create large vertical
spaces between text blocks.

The
|
|
|
|
.B iconvconfig
|
|
|
|
program reads iconv module configuration files and writes
|
2014-06-11 10:29:16 +00:00
|
|
|
a fast-loading gconv module configuration cache file.

|
|
|
In addition to the system provided gconv modules, the user can specify
|
2014-06-11 08:09:47 +00:00
|
|
|
custom gconv module directories with the environment variable
|
|
|
|
.BR GCONV_PATH .
|
2015-01-28 10:03:31 +00:00
|
|
|
However, iconv module configuration caching is used only when
|
2014-06-11 08:09:47 +00:00
|
|
|
the environment variable
|
|
|
|
.BR GCONV_PATH
|
|
|
|
is not set.
|
|
|
|
.SH OPTIONS
|
|
|
|
.TP
|
|
|
|
.B "\-\-nostdlib"
|
|
|
|
Do not search the system default gconv directory,
|
|
|
|
only the directories provided on the command line.
|
|
|
|
.TP
|
|
|
|
.BI \-o " outputfile" ", \-\-output=" outputfile
|
|
|
|
Use
|
|
|
|
.I outputfile
|
|
|
|
for output instead of the system default cache location.
|
|
|
|
.TP
|
|
|
|
.BI \-\-prefix= pathname
|
|
|
|
Set the prefix to be prepended to the system pathnames.
|
|
|
|
See FILES, below.
|
|
|
|
By default, the prefix is empty.
|
|
|
|
Setting the prefix to
|
|
|
|
.IR foo ,
|
|
|
|
the gconv module configuration would be read from
|
|
|
|
.IR foo/usr/lib/gconv/gconv-modules
|
|
|
|
and the cache would be written to
|
|
|
|
.IR foo/usr/lib/gconv/gconv-modules.cache .
|
|
|
|
