SHTK_CONFIG_RUN_HOOK(3) BSD Library Functions Manual SHTK_CONFIG_RUN_HOOK(3)NAMEshtk_config_run_hook — Executes a hook defined in a configuration file
LIBRARY
shtk_import config
SYNOPSISshtk_config_run_hook hook [arg1 .. argN]
DESCRIPTION
The shtk_config_run_hook function executes the function hook, defined by
the configuration file, in the same context as the file. Any arguments
arg1 to argN are passed literally to the hook. Hooks should not be exe‐
cuted directly because otherwise they would need to use the
shtk_config_get(3) familiy of functions to read the variables defined in
the file, which could be quite strange.
Keep in mind that the hook will only be able to access the configuration
variables previously registered with shtk_config_init(3). Any other
variables will be hidden and not available to the hook.
EXAMPLES
Consider the following configuration file:
SRCDIR=/usr/src
show_srcdir_hook() {
# Note that we can access SRCDIR directly, as would be normal in a
# configuration file. No need to use shtk_config_get.
echo "SRCDIR is ${SRCDIR}"
}
Then, we could process the file and execute the defined hook like this:
shtk_config_init SRCDIR
shtk_config_load ".../path/to/the/file/above.conf"
# This will print nothing because SRCDIR is not available here.
echo "SRCDIR is ${SRCDIR}"
# But this will display the right SRCDIR value.
shtk_config_run_hook show_srcdir_hook
ERRORS
Errors during the execution of the hook result in the termination of the
script.
