又写了一些函数，希望大家给指点一下。。。。小弟不胜感激。。。因为我是在利用ACE 在Linux下编写程序，看到ACE_DEBUG(( _ERROR ACE_TEXT( " delAllBlank execaption\n" ) )); 等是为了调试程序的方便写的。用的时候可以丢掉的。/*** wallwind 2011/8/31***十六进制转char。。。。 inthexToChar(string &value, char *buf, int &bufLen) { // ACE_DEBUG(( _INFO ACE_TEXT( "value:[%s]\n" ), value.c_str())); memset(buf, 0x00, bufLen); if ((unsigned int )bufLen < (value.length()/2)) { return -1; } if (value.length() == 0) { return -1; } if (value.length() % 2 != 0) { return -1; } int bufIndex = 0; for (unsigned int i = 0; i < value.length()/2; i++) { string tmp = value.substr(i*2, 2); ascToHex(tmp.c_str(), &buf[bufIndex], 2); bufIndex++; } bufLen = bufIndex; //ACE_HEX_DUMP((LM_INFO, (char *)buf, bufLen, "resp message:")); return 0; } asc转十六进制 intascToHex(const char *Asc, char *Hex, int AscLen) { char *HexPtr = Hex; short i; for(i = 0; i < AscLen; i++) { *HexPtr = Asc[i] << 4; if (!(Asc[i]>='0' && Asc[i]<='9')) *HexPtr += 0x90; i++; *HexPtr |= (Asc[i] & 0x0F); if (!(Asc[i]>='0' && Asc[i]<='9')) *HexPtr += 0x09; HexPtr++; } return 0; } //十六进制转asc inthexToAsc(const char *Hex, int HexLen, char *Asc) { int i; char *AscPtr; const char *HexPtr; char Temp; HexPtr=Hex; AscPtr=Asc; for(i = 0; i < HexLen; i++) { Temp = (*HexPtr & 0xf0) >> 4; if (Temp < 10) *AscPtr = 0x30 + Temp; // 数字0－9 else *AscPtr = 0x37 + Temp; // 字母A－F AscPtr++; Temp = *HexPtr & 0x0f; if (Temp < 10) *AscPtr = 0x30 + Temp; else *AscPtr = 0x37 + Temp; AscPtr++; HexPtr++; } return 0; } //删除字符串中的空格。 voiddelAllBlank(string &line) { if (line.length() <= 0) { return; } string tmp; tmp.clear(); try { for(unsigned int i = 0; i < line.length(); i++) { if (line[i] == ' ' || line[i] == '\t' || line[i] == '\n' || line[i] == '\r') { continue; } else { tmp += line[i]; } } line.clear(); line = tmp; } catch(...) { ACE_DEBUG(( _ERROR ACE_TEXT( " delAllBlank execaption\n" ) )); } return; } ///同上。 voiddelAllBlank(char *pstr) { if (NULL == pstr) { return; } int strLen = strlen(pstr); string tmpStr; try { for(int i = 0; i < strLen; i++) { if (pstr[i] == ' ' || pstr[i] == '\t' || pstr[i] == '\n' || pstr[i] == '\r') { continue; } else { tmpStr += pstr[i]; } } } catch(...) { ACE_DEBUG(( _ERROR ACE_TEXT( " delAllBlank execaption\n" ) )); } memset(pstr, 0x00, strLen); memcpy(pstr, tmpStr.c_str(), tmpStr.length()); return; } /删除最后一个空格 voiddelLastBlank(char *pstr) { if (NULL == pstr) { return; } string tmpStr = pstr; memset(pstr, 0x00, strlen(pstr)); try { for (;;) { if (tmpStr.length() > 0) { if (tmpStr[tmpStr.length()-1] == ' ' || tmpStr[tmpStr.length()-1] == '\t' || tmpStr[tmpStr.length()-1] == '\n' || tmpStr[tmpStr.length()-1] == '\r') { tmpStr.erase(tmpStr.length()-1); } else { break; } } else { break; } } } catch(...) { ACE_DEBUG(( _ERROR ACE_TEXT( " delLastBlank execaption\n" ) )); } memcpy(pstr, tmpStr.c_str(), tmpStr.length()); return; } voiddelLastBlank(string &tmpStr ) { try { for (;;) { if (tmpStr.length() > 0) { if (tmpStr[tmpStr.length()-1] == ' ' || tmpStr[tmpStr.length()-1] == '\t' || tmpStr[tmpStr.length()-1] == '\n' || tmpStr[tmpStr.length()-1] == '\r') { tmpStr.erase(tmpStr.length()-1); } else { break; } } else { break; } } } catch(...) { ACE_DEBUG(( _ERROR ACE_TEXT( " delLastBlank execaption\n" ) )); } return; } 删除最前边的空格。 voiddelHeadBlank(string &tmpStr ) { try { for (;;) { if (tmpStr.length() > 0) { if (tmpStr[0] == ' ' || tmpStr[0] == '\t' || tmpStr[0] == '\n' || tmpStr[0] == '\r') { tmpStr.erase(0); } else { break; } } else { break; } } } catch(...) { ACE_DEBUG(( _ERROR ACE_TEXT( " delLastBlank execaption\n" ) )); } return; } //加载文件。 intloadFile(string fileName, vector<string> &vecLine) { vecLine.clear(); FILE *m_fp = fopen(fileName.c_str(), "rb"); if (NULL == m_fp) { ACE_DEBUG(( _ERROR ACE_TEXT( " getline execpaction:[%s]\n" ), fileName.c_str())); return -1; } char fileLine[MAX_FILE_LINE_LEN]; try { for (;;) { memset(fileLine, 0x00, MAX_FILE_LINE_LEN); if (!feof(m_fp)) { if (NULL == fgets(fileLine, MAX_FILE_LINE_LEN, m_fp)) { break; } vecLine.push_back(fileLine); } else { break; } } } catch(...) { fclose(m_fp); ACE_DEBUG(( _ERROR ACE_TEXT( " getline execpaction:[%s]\n" ), fileName.c_str())); return -1; } fclose(m_fp); return 0; } 写到文件 void writeToFile(string fileName, char *format, ...) { va_list ap; char date[10240]; char msgformat[10240]; memset(msgformat, 0x00, 10240); memset(date, 0x00, 10240); FILE *logfp = NULL; logfp = fopen(fileName.c_str(), "a+"); if (NULL == logfp) { printf("open log file fail.\n"); return ; } if (NULL == format) { printf("NULL == format.\n"); } strcat(msgformat, format); int msglen = strlen(msgformat); if ('\n' != msgformat[msglen - 1]) { strcat(msgformat, "\n"); } va_start(ap, format); vfprintf (logfp, msgformat, ap); va_end(ap); fflush(logfp); fclose(logfp); return; }
