Hello,
How do I export a change to an environment variable made in a C program?
I tried setenv() and putenv(), but the change is not visible to the shell.
////////// testenv.c
int main(int argc, char* argv[], char* envp[])
{
char* p;
p = getenv("MyTest");
printf("current value: %s\n", p);
setenv("MyTest", "New value here", 1);
p = getenv("MyTest");
print("new value: %s\n", p);
return 0;
}
/////////
I compiled the code and test in a bash shell:
$>export MyTest="Current Value"
$>./testenv
current value: Current Value
new value: New value here
$>echo $MyTest
Current Value
The old value is retained.
Thanks for your help.
Regards,
Nemo Mai
