I am calling one c++ exe from my unix shell script, i am trying to set the env variables using putenv() thru my c++ code. Now i want to use these varibles in my new exe which is there in the same shell script(set by using the previous exe ) , but i am not able to access those varibles..
Please help me out in this.
flow of the script. :
one c++ exe (putenv("ABC=a") variable)
|
(when i am doing echo $ABC in the script i am not able to get its value and also i am not able to getenv this variable value)
|
V
second c++ exe of different version compiler (Here i want to get the already set env variables.)
>> am not able to do that
Yup -- you found out the hard way that it can't be done. One solution is to write the variables to a file or shared memory so that other programs can read them.
