main.c:588: poor error checking ?

[David Binderman <linuxdev.baldrick@xxxxxxxxx>]

Hello there,

main.c:588]: (style) Checking if unsigned variable 'bytes' is less than zero.

Source code is

       bytes = read(fd, buf, size);
        if (bytes < 0) {

but

    uint32_t bytes;

and the return type of read is int. Suggest code rework.

Regards

David Binderman
