how to pass variable arguments from one function to other in tcl
- by vaichidrewar
I want to pass variable arguments obtained in one function to other function but I am not able to do so. Function gets even number of variable arguments and then it has to be converted in array. Below is the example.
Procedure abc1 gets two arguments (k k) and not form abc1 procedure these have to be passed to proc abc where list to array conversion it to be done. List to array conversion works in proc1 i.e. abc1 but not in second proc i.e. abc
Error obtained is given below
proc abc {args} {
puts "$args"
array set arg $args
}
proc abc1 {args} {
puts "$args"
array set arg $args
set l2 [array get arg]
abc $l2
}
abc1 k k
abc k k
Output:
k k
{k k}
list must have an even number of elements
while executing
"array set arg $l1"
(procedure "abc" line 8)
invoked from within
"abc $l2"
(procedure "abc1" line 5)
invoked from within
"abc1 k k"
(file "vfunction.tcl" line 18)
