gen_ctab.c

我搜集到的一个java常用类库的源代码

/*
 * generate b2g_tables.c file for hztty
 */

#include<stdio.h>

main(argc,argv)
  int argc;
  char *argv[];
{
	if (argc != 3) {
		fprintf (stderr, "Usage: %s map_file variable_name\n", *argv);
		exit (1);
	}
	gen (argv[1], argv[2], stdout);
	exit (0);
}

gen(file,varname,of)
     char *file;
     char *varname;
     FILE *of;
{
  FILE *f;
  char buf[80];
  int c1, c2;
  int count = 0;

	f = fopen (file, "r");
	if (! f) {
		perror (file);
		exit (1);
	}

	fprintf (of, "unsigned char %s[] = {\n", varname);

	while (1) {
		c1 = getc (f);
		c2 = getc (f);
		if (c1 == EOF || c2 == EOF)  break;
		fprintf (of, "0x%x,0x%x,", c1, c2);
		if ((++count % 7) == 0)
			putc ('\n', of);
		else
			putc (' ', of);
		if (getc(f) == EOF)	/* to eat the '\n' */
			break;
	}
	fprintf (of, "\n");
	fprintf (of, "};\n"); 
	fprintf (of, "int %s_count = %d;\n", varname, count);
	fprintf (of, "\n");
}
