Rom.c中的程序主要是对rom方式存放的web page进行处理。
Webcomp.c主要是对将web page转换为rom形式，转换后的web page为webrom.c
Webrom.c文件中存放着各个页面。
websRomPageIndexType websRomPageIndex[]是一个数组，结构体为：
typedef struct {
char_t *path; /* Web page URL path */
unsigned char *page; /* Web page data */
int size; /* Size of web page in bytes */
int pos; /* Current read position */
} websRomPageIndexType;
例如：
websRomPageIndexType websRomPageIndex[] = {
{ T("/css/style.css"), page_0, 3578 },
{ T("/css/tree.css"), page_1, 300 },
{ T("/eth.asp"), page_2, 6404 },
{ T("/ethglobal.asp"), page_3, 2927 },
{ T("/global.asp"), page_4, 868 },
{ T("/images/empty.gif"), page_5, 834 },
{ T("/images/join.gif"), page_6, 870 },
{ T("/images/joinbottom.gif"), page_7, 856 },
{ T("/images/line.gif"), page_8, 856 },
{ T("/images/logo.gif"), page_9, 1545 },
{ T("/images/minus.gif"), page_10, 872 },
{ T("/images/minusbottom.gif"), page_11, 868 },
{ T("/images/nolines_minus.gif"), page_12, 859 },
{ T("/images/nolines_plus.gif"), page_13, 862 },
{ T("/images/plus.gif"), page_14, 873 },
{ T("/images/plusbottom.gif"), page_15, 869 },
{ T("/index.asp"), page_16, 2965 },
{ T("/index.htm"), page_17, 3119 },
{ T("/js/common.js"), page_18, 1103 },
…..
{ 0, 0, 0 },
}
分别对应page的路径、page数据的字符数组、page中字符数量。
static unsigned char page_0[] = {
98,111,100,121, 44, 32,116, 97, 98,108,101, 44, 32,116, 97, 98,
108,101, 32,116,100, 32,123, 10, 32, 32, 32, 32,102,111,110,116,
45,102, 97,109,105,108,121, 58, 32, 34, 72,101,108,118,101,116,
105, 99, 97, 34, 59, 10,125, 10, 10, 98,111,100,121, 32,123, 10,
32, 32, 32, 32,102,111,110,116, 45,115,105,122,101, 58, 32, 57,
112,116, 59, 10, 32, 32, 32, 32, 98, 97, 99,107,103,114,111,117,
110,100, 45, 99,111,108,111,114, 58, 32, 35, 68, 65, 69, 56, 70,
。。。。
}
Page_0就是"/css/style.css"的数据。
int websRomOpen()
功能：打开rom模块
说明：
-----------------------------------------------------------------------------------------------------------------
void websRomClose()
功能：关闭rom模块。
说明：
-----------------------------------------------------------------------------------------------------------------
int websRomPageOpen(webs_t wp, char_t *path, int mode, int perm)
功能：打开一个page
说明：
-----------------------------------------------------------------------------------------------------------------
int websRomPageStat(char_t *path, websStatType *sbuf)
功能：查询page的stat信息。
说明：
-----------------------------------------------------------------------------------------------------------------
int websRomPageReadData(webs_t wp, char *buf, int nBytes)
功能：读取rom中page到buf中。
说明：
-----------------------------------------------------------------------------------------------------------------
long websRomPageSeek(webs_t wp, long offset, int origin)
功能：移动到page中的某个位置
说明：
-----------------------------------------------------------------------------------------------------------------
Webcomp.c中的程序在linux下能编译通过、跑起来。
int main(int argc, char* argv[])
功能：主程序
说明：输入命令时需要两个参数，./webcomp prefix filelist >webrom.c，prefix是page所在的目录，filelist是page目录名称文件，>webrom.c是生成的rom文件。
一般可以这样
find ../web1 –name "*.*" > websfile
./webcomp ../web1 websfile > ../webrom.c
websfile中的内容是：
web1/css/style.css
web1/css/tree.css
web1/eth.asp
web1/ethglobal.asp
web1/global.asp
web1/images/empty.gif
….
-----------------------------------------------------------------------------------------------------------------
static void usage()
功能：说明语句。
说明：
-----------------------------------------------------------------------------------------------------------------
static int compile(char *fileList, char *prefix)
功能：转换生成rom文件的主程序。
说明：生成webrom.c文件
-----------------------------------------------------------------------------------------------------------------
由于感觉webcomp.c只是linux下程序，所以修改了一下，转换成windows下的程序。

然后编写了bat文件，内容是：
webcomp.exe web1 > src\webrom.c
即将web1目录下page转换成webrom.c了。
