测试：

int main (void){    char *pString = "1234;123.112.123.123:8081;GPSDATA;;60;19200;8;N;1;N";    char *pStrTmp[20]={NULL};    int i=0;    pStrTmp[i] = strsep(&pString,";");    while((pStrTmp[i] != NULL)&&(i<19))
　　{         i++;         pStrTmp[i] = strsep(&pString,";");          printf("pStrTmp[%d] = %s\n",pStrTmp[i] );   }   return 0;
}

运行结果:pStrTmp[0] = "1234";pStrTmp[1] = "123.112.123.123:8081";pStrTmp[2] = "GPSDATA";pStrTmp[3] = "";pStrTmp[4] = "60";pStrTmp[5] = "19200";pStrTmp[6] = "8";pStrTmp[7] = "N";pStrTmp[8] = "1";pStrTmp[9] = "N";
