int main ()
{
char szNumbers[] = "2001 60c0c0 -1101110100110100100000 0x6fffff";
char *pEnd;
long int li1, li2, li3, li4;
li1 = strtol (szNumbers, &pEnd, 10);
printf("pEnd = %sn", pEnd);
li2 = strtol (pEnd, &pEnd, 16);
printf("pEnd = %sn", pEnd);
li3 = strtol (pEnd, &pEnd, 2);
printf("pEnd = %sn", pEnd);
li4 = strtol (pEnd, NULL, 0);
printf ("The decimal equivalents are: %ld, %ld, %ld and %ld.n", li1, li2, li3, li4);
return 0;
}运行结果：
pEnd = 60c0c0 -1101110100110100100000 0x6fffff pEnd = -1101110100110100100000 0x6fffff pEnd = 0x6fffff The decimal equivalents are: 2001, 6340800, -3624224 and 7340031.
从结果中可以看出，pEnd是转换后剩余的字符串
