+ * Name: env_dup
+ *
+ * Description:
+ *   Copy the internal environment structure of a task.  This is the action
+ *   that is performed when a new task is created:
+ *   The new task has a private, exact duplicate of the parent task's
+ *    environment.
+ *
+ * Input Parameters:
+ *   group - The child task group to receive the newly allocated copy of the
+ *           parent task groups environment structure.
+ *
+ * Returned Value:
+ *   zero on success
+ *
+ * Assumptions:
+ *   Not called from an interrupt handler.

+ *   a task group exits.  The env_release() function clears the environment
+ *   of all name-value pairs and sets the value of the external variable
+ *   environ to NULL.
+ *
+ * Input Parameters:
+ *   group - Identifies the task group containing the environment structure
+ *           to be released.
+ *
+ * Returned Value:
+ *   None

+ *   group - The task group containing environment array to be searched.
+ *   pname - The variable name to find
