SYNOPSIS

#include <stdlib.h>

char ∗getenv(char ∗name);

DESCRIPTION

Getenv searches the environment list (see environ(7)) for a string of the form name=value and returns a pointer to the string value if such a string is present, otherwise getenv returns the value 0 (NULL). 

RETURN VALUE

Upon successful completion, getenv returns a pointer to a string containing the value for the specified name, or a NULL pointer if the specified name cannot be found.  Unsuccessful completion results in the return of a NULL pointer.
