opt2byte.LIB命令行开关解析库

THE OPT TO BYTE ARRAY LIB, COPYRIGHT@2016~2018 BY HAPPY, VERSION 1.0
opt2byte.LIB

摘要：
=============================================================================
这是可以解析命令行参数的库，用来帮助你快速构建命令行第三方工具的开关解析部分。
从此你无需再写开关解析。
=============================================================================


函数原型:
-----------------------------------------------------------------------------
//OPT转BYTE数组
byte* __cdecl Opt2Byte(
        int argc,                                  //argc
        char** argv,                           //argv
        char* optstr                            //开关正则
);
-----------------------------------------------------------------------------


引入：
-----------------------------------------------------------------------------
#include "opt2byte.h"                            //先引入头文件
#pragram commet(lib,"opt2byte.LIB");  //在项目中引入库文件
-lopt2byte -L./                                       //gcc连接参数
-----------------------------------------------------------------------------


命令开关正则语法：
-----------------------------------------------------------------------------
char* optstr="=/C* /U:utf-8  /CS /T* /D* /M* /?";

在上句opt正则中，其中第一个引号后的等号表示精确开关匹配，
即区分大小写匹配，不为等号则忽略大小写匹配。

其中*代表后继参数，一个*代表/C开关有一个后继参数。
其中:代表连参符，即/U开关后边无需空格即可连接参数，如/U:"utf-8"。
其中无*的开关表示没有任何后继参数。

opt2byte.LIB库，最大可支持99个开关解析，最多处理254个命令行参数。 当然你可以
在源码中修改以使其支持不限量的数目。

opt2byte.LIB库全部为本人原创，且不需要任何其他库文件，效率性能秒杀getopt函数，
无法解析的开关argv[unknown]将存入bp[100~127]的无法解析空间。 bp[0]表示解析状
态，即bp[0]为0时表示正常解析，否则其值为发生错误的argv序号。bp[1~99]为各开关
解析到的命令行参数argv序号。

-----------------------------------------------------------------------------
This is a library of command-line arguments  that can  help you quickly build
switch-resolution parts of command-line third-party tools.From then on you do
not have to repeat the write switch every time parsing.

使用示例：
#include <stdio.h>
#include "opt2byte.h"
 
int main(int argc, char** argv)

	byte* bp=Opt2Byte(argc, argv, optstr);                   //这里用来接收转化后的BYTE数组
 
	if(bp[0]==255){printf("没有任何参数\n");}
	if(bp[0]!=0){printf("在%s附近出现错误，可能是缺少参数，或是无法解析的开关\n", argv[bp[0]]);}
                   
	for(i=1; i<=4; i++){printf("%d\n",bp[i]); }            //打印分析后的开关BYTE数组参数
 
	return 0;
