Example:
Note that this example uses
TokenizeSymName
and not
TokenizeName
which does not work for folder names.
void DelFold( BYTE *foldName ) {
EStackIndex oldTop = top_estack; /* save top of ESTACK */
TRY
push_quantum (END_TAG); /* mark end of parameter list */
if (TokenizeSymName( foldName, 0 ) == NULL) /* push tokenized name on ESTACK */
ER_THROW( INVALID_PATHNAME_ERROR );
cmd_delfold(top_estack);
top_estack = oldTop; /* restore top of ESTACK */
ONERR
top_estack = oldTop; /* restore top of ESTACK */
PASS; /* pass error on up to caller */
ENDTRY
}
