Message-ID: <363801FFD7B74240A329CEC3F7FE4CC40D3383@ntxboimbx07.micron.com> (raw)
You can also declare your programs main function as
int main(int argc, char** argv, char** env)
You will then get your environment variables as a zero-terminated array
of character pointers, pointing to variable-value pairs in the format
VARIABLE=value
That will give you access to every environment variable defined in your
program's environment.
Thanks,
Lyle Taylor

Hi Bharati,
Could you give some more details about it.... like return type etc.
Anyways, i just tried : char* x = environ();
it gave me an error saying environ() cannot be used as a function.
