SYNOPSIS

ment variable(s).
The variable argument is the name of the environment variable to get.
The value argument is the value of the environment variable. If no
value (in other words, (char *)0) is returned for this argument, then
the variable was not present in the handler's environment. This condi‐
tion is not an error. If an empty string (in other words, "") is
returned for this argument, then the variable was present in the han‐
dler's environment, but had a null value.
