No, a process can't modify the environment of its parent (and the parent of a
program is typically a shell). You could have the program output the desired
environment variable contents and do
% YOURENVVAR=`yourprogramname`

You might want to try setenv(). Just type 'man 3 setenv' in a Linux
shell to get the man-page for that function (which is in stdlib).

Unless one wants to set a persistant value, that can be used after his/hers
process finishes...
Unfortunately functions like setenv(), putenv(), system("export ...") change
only the current environment of the process itself, not the 'global'
environment of the user (let alone the system).

Hi,
I have tried some experiments along these lines.
#include

char *rc;
FILE *fp;
char buffer[256];
putenv("FRED=\"Hello World\"");
rc = getenv("FRED");
if(rc)
printf("rc: %s\n", rc);
else
printf("Not found\

fprintf(fh, "EVR=\"%s\"\n", getenv("EVR"));
fclose(fh);
}

This is overly complex. The initial setting of env var EVR at the beginning of
the script does nothing, and the C program is just using the environment t
