NAME

getenv − return value for environment name

SYNOPSIS

char ∗getenv (name)
char ∗name;

DESCRIPTION

Getenv searches the environment list (see environ(5)) for a string of the form name=value, and returns a pointer to the value in the current environment if such a string is present, otherwise a NULL pointer.  Name may be either the desired name, null-terminated, or of the form name=value, in which case getenv uses the portion to the left of the "=" as the search key.
