iconvconfig - create iconv module configuration cache
iconvconfig [
options] [
directory]...
The
iconv(3) function internally uses
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 programs that use
iconv(3), so a caching mechanism is
employed.
The
iconvconfig program reads iconv module configuration files and writes
a fast-loading gconv module configuration cache file.
In addition to the system provided gconv modules, the user can specify custom
gconv module directories with the environment variable
GCONV_PATH.
However, iconv module configuration caching is used only when the environment
variable
GCONV_PATH is not set.
- --nostdlib
- Do not search the system default gconv directory, only the directories
provided on the command line.
- -o outputfile, --output=outputfile
- Use outputfile for output instead of the system default cache
location.
- --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 foo, the
gconv module configuration would be read from
foo/usr/lib/gconv/gconv-modules and the cache would be written to
foo/usr/lib/gconv/gconv-modules.cache.
- -?, --help
- Print a usage summary and exit.
- --usage
- Print a short usage summary and exit.
- -V, --version
- Print the version number, license, and disclaimer of warranty for
iconv.
Zero on success, nonzero on errors.
