Unlike 'int_arg' which accepts full range of 64bit number this function will error on numbers out of this range: <0, UINT32_MAX> --- tools/lvmcmdline.c | 8 ++++++++ tools/tools.h | 1 + 2 files changed, 9 insertions(+), 0 deletions(-) diff --git a/tools/lvmcmdline.c b/tools/lvmcmdline.c index 9a4deb7..ae26957 100644 --- a/tools/lvmcmdline.c +++ b/tools/lvmcmdline.c @@ -554,6 +554,14 @@ int int_arg(struct cmd_context *cmd __attribute__((unused)), struct arg_values * return 1; } +int uint32_arg(struct cmd_context *cmd, struct arg_values *av) +{ + if (!int_arg(cmd, av) || (av->ui64_value > UINT32_MAX)) + return 0; + + return 1; +} + int int_arg_with_sign(struct cmd_context *cmd __attribute__((unused)), struct arg_values *av) { char *ptr; diff --git a/tools/tools.h b/tools/tools.h index f6d224f..1419af9 100644 --- a/tools/tools.h +++ b/tools/tools.h @@ -144,6 +144,7 @@ int size_kb_arg(struct cmd_context *cmd, struct arg_values *av); int size_mb_arg(struct cmd_context *cmd, struct arg_values *av); int size_mb_arg_with_percent(struct cmd_context *cmd, struct arg_values *av); int int_arg(struct cmd_context *cmd, struct arg_values *av); +int uint32_arg(struct cmd_context *cmd, struct arg_values *av); int int_arg_with_sign(struct cmd_context *cmd, struct arg_values *av); int int_arg_with_sign_and_percent(struct cmd_context *cmd, struct arg_values *av); int major_arg(struct cmd_context *cmd, struct arg_values *av);
