Arguments are the name * of the file where the strings are to be placed, the * prefix of the new files where the processed source text * is to be placed, and the files to be processed. * * The program looks for 'error("' in the source stream. * Whenever it finds this, the following characters from the '"' * to a '"' are replaced by 'seekpt' where seekpt is a * pointer into the error message file. * If the '(' is not immediately followed by a '"' no change occurs. * * The optional '-' causes strings to be added at the end of the * existing error message file for recompilation of single routines. */ #include #include #include #include #include #define ungetchar(c) ungetc(c, stdin) #define NBUCKETS 511 static char usagestr[] = "usage: %s [ - ] mesgfile prefix file ...\n"; static FILE *mesgread, *mesgwrite; static void process(void); static int match(char *ocp); static void copystr(void); static int octdigit(char c); static void inithash(void); static int hashit(char *str, char really, unsigned int fakept); static int fgetNUL(char *obuf, int rmdr, FILE *file); int main(int argc, char *argv[]) { char addon = 0; char *progname, *np, name[MAXPATHLEN]; size_t size = 0; size_t len; (void) setlocale(LC_ALL, ""); #if !defined(TEXT_DOMAIN) #define TEXT_DOMAIN "SYS_TEST" #endif (void) textdomain(TEXT_DOMAIN); argc--, progname = *argv++; if (argc > 1 && argv[0][0] == '-') addon++, argc--, argv++; if (argc < 3) (void) fprintf(stderr, gettext(usagestr), progname), exit(1); mesgwrite = fopen(argv[0], addon ?
