-FUNCTION
-<<_getenv_r>>---look up environment variable
-
-INDEX
-	_getenv_r
-INDEX
-	environ
-
-ANSI_SYNOPSIS
-	#include <stdlib.h>
-	char *_getenv_r(struct _reent *<[reent_ptr]>, const char *<[name]>);
-
-TRAD_SYNOPSIS
-	#include <stdlib.h>
-	char *_getenv_r(<[reent_ptr]>, <[name]>)
-	struct _reent *<[reent_ptr]>;
-	char *<[name]>;
-
-DESCRIPTION
-<<_getenv_r>> searches the list of environment variable names and values
-(using the global pointer ``<<char **environ>>'') for a variable whose
-name matches the string at <[name]>.  If a variable name matches,
-<<_getenv_r>> returns a pointer to the associated value.
-
-RETURNS
-A pointer to the (string) value of the environment variable, or
-<<NULL>> if there is no such environment variable.
-
-PORTABILITY
-<<_getenv_r>> is not ANSI; the rules for properly forming names of environment
-variables vary from one system to another.
-
-<<_getenv_r>> requires a global pointer <<environ>>.
