I want to take an integer value from one shell-variable and pass a
modified value to another shell-variable. First I tried setint_v (after
using local to get tbl structures for the two shell-variables) and
second I tried various forms of the var.c functions intval & setint .
To see if things worked, I print the shell-variable (to which I assigned a
value) afterwards, but neither path seems to have succeeded. I may try
getint next, and also make my tests more basic, but if anyone could give me
a good hint, I'd appreciate it.
One thing that puzzles me is can be illustrated by the following code:
struct tbl *var1 ;
int val1 ;
var1 = local( "LINENO" , FALSE ) ;
getint( var1 , &val1 ) ;
printf( "%d %d\n" , var1->val.i , val1 ) ;
which gives differing values in the two fields (the val1 value appears to
be correct). Isn't val.i (from struct tbl ) where the integer (or is it
floating point?, but it is declared long ) is stored?
Please send a response directly to me, my bulk-mail folder is
over-stuffed.
