The functions error's numbers are standarized - but the error messages are not. The errors are often handled with unclear error messages, so why not use an errno standarized messages. Advantages: - This could decrease the binary size. - Appended with a detailed information, the error message will be clear. This commit introduces new function: - const char *errno_to_str(int errno) The functions returns a pointer to the errno corresponding text message: - if errno is null or positive number - a pointer to "Success" message - if errno is negative - a pointer to errno related message Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Reviewed-by: Tom Rini <trini@ti.com>
