Hello list, While reviewing some the vendor library source I found that Mellanox and Pathscale user-space provider library returns positive error number if any immediate error is encountered. However, other vendor user-space libraries return negative error numbers. Is there any guideline on this topic. If not, what is the correct way to do this. Taking reference of glibc implementation, I found that it expects negative integer as return value. Any pointer/reference/guideline will be a great help. -Regards Devesh -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
