env[] in main()

[vb.bajpai]

referring to http://www.math.ntnu.no/~hrue/GMRFsi...ple-approx-2.c

i fount the main() to be as

int main(int argc, char **argv, char **env)

Can someone explain me, where is env used and for what purpose?

[robwhit]

in certain borland compilers and maybe others, it's used to pass environment variables to the program. It's non-standard though. See the faq.

See the faq.[/QUOTE]

from the FAQ :-

int main(int argc, char *argv[], char *envp[])

shouldnt it be char *env[] than char *envp[] ??

[robwhit]

as long as the types are the same, it doesn't really matter.

int main(int sdgf, char *dslkgjf[])

would work too, it's just convention.

See MSDN too, they provide a pretty good explanation: http://msdn2.microsoft.com/en-us/lib...sc(VS.71).aspx
