The third arg to strtol() specifies the base to assume for the number. When 0 is passed, as is currently done in option-parser.c, hexadecimal and octal numbers are permitted and automatically detected and converted. In weston and the weston clients and tests using option-parser.c, the options are all things that can be expected to be specified in base 10: widths, heights, counts, scales, font sizes, ports, ttys, connectors, etc. The subsurfaces client uses two modes, limited to values 0 and 1 only. The zuc testsuite has a --random parameter for specifying a seed, which is the only option where using hexadecimal or octal numbers might conceivably happen. The benefit of limiting this to base-10 is to eliminate surprises when parsing numbers from the command line. Also, by making the code consistent with other usages of strtol/strtoul, it may make it possible to factor out the common code in the future. Signed-off-by: Bryce Harrington <bryce@osg.samsung.com> |
