- * Name: env_removevar
- *
- * Description:
- *   Remove the referenced name=value pair from the environment
- *
- * Parameters:
- *   group The task group with the environment containing the name=value pair
- *   pvar A pointer to the name=value pair in the restroom
- *
- * Return Value:
- *   Zero on success
- *
- * Assumptions:
- *   - Not called from an interrupt handler
- *   - Caller has pre-emptions disabled
- *   - Caller will reallocate the environment structure to the correct size
