Q.
Is there a function I can call from my NLM that will return a list of variables that are normally accessed by LIBC@getenv()?
A.
Here are two approaches. You can either do something like:
#include <stdio.h>
#include <stdlib.h>
#include <screen.h>
int main( int argc, char* argv[], char*
environ[]) {
int i;
for ( i = 0; i < argc; ++i) printf( "argv[ %d] = %s\n", i, argv[ i]);
for ( i = 0; environ[ i] != NULL; ++i) printf( "environ[ %d] = %s\n", i,
environ[ i]);
pressanykey();
return EXIT_SUCCESS;
}
Or you can access the global environ
variable:
extern char **environ;
char **p;
for (p = environ; *p; ++p)
fprintf(stdout, "\t%s\n", *p);
