◆ GNUNET_CONFIGURATION_expand_dollar()

char* GNUNET_CONFIGURATION_expand_dollar ( const struct GNUNET_CONFIGURATION_Handle cfg,

)

Expand an expression of the form "$FOO/BAR" to "DIRECTORY/BAR" where either in the "PATHS" section or the environtment "FOO" is set to "DIRECTORY".

We also support default expansion, i.e. ${VARIABLE:-default} will expand to $VARIABLE if VARIABLE is set in PATHS or the environment, and otherwise to "default". Note that "default" itself can also be a $-expression, thus "${VAR1:-{$VAR2}}" will expand to VAR1 and if that is not defined to VAR2.

Parameters
cfgconfiguration to use for path expansion
origstring to $-expand (will be freed!) Note that multiple $-expressions can be present in this string. They will all be $-expanded.
Returns
$-expanded string
