So would I. If I was trying to implement the original arrangement
properly, I'd probably do it something like this...
---BEGIN---
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <getopt.h>
#include <libintl.h>
#define _(x) gettext(x)
#define VERSION "0.1"
void
somefunction(char *strout, int n)
{
strncpy(strout, _("some words"), n);
strout[n-1]='\0';
}
void
usage(int argc, char *argv[])
{
fprintf(stderr,_("%s: do stuff\n\n"), argv[0]);
fprintf(stderr,_("usage:\n %s [<flags>]\n\n"), argv[0]);
fprintf(stderr,_("valid flags:\n"));
fprintf(stderr,_(" -h, --help display this message\n"));
fprintf(stderr,_(" -v, --version display the version number\n"));
exit(1);
}
void
version(int argc, char *argv[])
{
fprintf(stderr, _("%s: version %s\n"), argv[0], VERSION);
exit(1);
}
static struct option opts[] = {
{"help", no_argument, NULL, 'h'},
{"version", no_argument, NULL, 'v'},
{NULL, 0, NULL, 0}
};
#ifndef BUF
#define BUF 256
#endif
int
main (int argc, char *argv[])
{
char string[BUF];
int c;
while (-1 != (c = getopt_long(argc, argv, "hv", opts, NULL))) {
switch (c) {
case 'v':
version (argc, argv);
break;
case 'h':
usage (argc, argv);
break;
default:
break;
}
}
somefunction(string, BUF);
printf (_("\n\nString is: %s\n\n"), string);
return 0;
}
---END---
Thus keeping the i18n and GNU people happy too!
C.
