Subject: parse-options: add new function "usage_msg_opt"
X-Git-Tag: v1.6.5-rc0~52^2~4
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/451bb210f81c10b60bf90403c9183be26beaaabf?hp=451bb210f81c10b60bf90403c9183be26beaaabf

parse-options: add new function "usage_msg_opt"

This function can be used instead of "usage_with_options" when you
want to print an error message before the usage string.

It may be useful because:

if (condition)
usage_msg_opt("condition is false", usage, opts);

is shorter than:

if (condition) {
fprintf(stderr, "condition is false\n\n");
usage_with_options(usage, opts);
}

and may be more consistent.
