shtk_config_has —
Checks if a configuration variable is set
shtk_import config
shtk_config_has |
var_name |
The shtk_config_has function checks if the
configuration variable var_name has been previously
set by a call to
shtk_config_set(3) within
the script or by the user in the configuration file.
Note that shtk_config_has properly
distinguishes the case between a variable that has never been defined and a
variable that has been defined to the empty value.
Returns 0 (true) if var_name has been defined; 1 (false) otherwise.
shtk_config_has first appeared in
shtk 1.0.
