C & getenv

[cl333r]

Hi,
does anyone know why I get the warning "main.c:29: warning: initialization makes pointer from integer without a cast" for line


char *home = getenv("HOME");

and writing "char *home = (char *)getenv("HOME");" cancels the warning. The API states that a (char *) is being returned from getenv, why do I have to explicitly cast it?

Maybe because you forgot to include <stdlib.h>?

P.S. You should also consider declaring your variable as a const char*.


const char* home = getenv("HOME");

Thanks, that solved the issue.
