写一下这2天的彩信收发心的，有自己的部分，也有部分代码用的别人的。

发彩信可以调用系统提供的接口，也可以自己通过socket http连接彩信网关2种方法来发送彩信。方法1 利用socket彩信发送：格式大概为 http包头+mm1，xml的彩信数据#include "ril.h"#pragma comment(lib,"ril.lib") //自己下载intget_mms_packet(char* mms_context, char* context, int context_len, char* mobile_id){char szToCombin[50];char*  pSubject = "MmsTest";int iDataTextLen;char *szXmlFileName = "my.txt";char *id = "9604059";//X-Mms-Message-Type(0x8c): m-send-req(0x80)unsigned char* pCurPos = mms_context;*pCurPos = 0x8c;

pCurPos++;strcpy( (char*)pCurPos, szToCombin);pCurPos += strlen(szToCombin);*pCurPos = 0x00; pCurPos++;//subject*pCurPos = 0x96; pCurPos++;strcpy( (char*)pCurPos, pSubject );pCurPos += strlen(pSubject);*pCurPos = 0x00;
