SHTK_CONFIG_HAS(3) FreeBSD Library Functions Manual SHTK_CONFIG_HAS(3)

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(3), shtk_config(3)

shtk_config_has first appeared in shtk 1.0.
November 6, 2014 FreeBSD 13.1-RELEASE
