SYNOPSIS

shtk_config_has var_name

DESCRIPTION

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.

RETURN VALUES

Returns 0 (true) if var_name has been defined; 1 (false) otherwise.

shtk_config_has first appeared in shtk 1.0.
