这是一段打印 结构数据的日志,以下为 相应日志打印效果

上述日志数据中,每行展示了 20 个字符,方便用户做数据定位,同时右边部分 ASCII 方式展示,比较好的处理了汉字问题,多数汉字都可以看到。
以下为具体程序实现
#define HEXLEN 20 /* 十六进制日志字符数 */ struct HEXBUF { int point; /* 数据显示位置 */ int chn ; /* 汉字标识 */ char scop[ 6 + 1 ]; /* 位置偏移数 */ char sstr[ 20 + 1 ]; /* ASCII 打印串 */ char shex[ 61 + 1 ]; /* 十六进制打印串 */ } ; /* ** 十六进制打印缓冲区初始化 */ void HexBuf_init(struct HEXBUF *p ) { p->point = 0; memset(p->scop, 0x0 , sizeof(p->scop)); memset(p->sstr, 0x20, HEXLEN ); memset(p->shex, 0x20, HEXLEN*3 ); return ; } /* ** 定长数据包 十六进制打印程序 */ int printHexLog( void *PInfo, char *Title, int mLen) { int cnt; // 当前数据处理位置 int point ; char temp[5]; unsigned char *ptr = (unsigned char *) PInfo ; struct HEXBUF hex; memset(&hex, 0x0, sizeof(hex)); printf( "%25s------- %s (%d) ------- \n", "", Title, mLen); HexBuf_init(&hex); for( cnt = 0; cnt < mLen ; cnt ++, ptr ++ ) { if(hex.point && (cnt % HEXLEN) == 0 ) { hex.chn = hex.chn & 0x01; if( hex.chn ) hex.sstr[HEXLEN-1]='.'; printf("%s: %s | %s |\n", hex.scop, hex.shex, hex.sstr); HexBuf_init( &hex ); } if(hex.point == 0 ) sprintf(hex.scop, "%04d", cnt ); point = hex.point; if( (*ptr) < 0x20 ) hex.sstr[point] = '.'; else { if(point == 0 && hex.chn ) { hex.chn = 0; hex.sstr[0] = '.'; } else { hex.sstr[point] = (*ptr); if( (*ptr & 0x80) == 0x80 ) hex.chn ++ ; } } point *= 3; sprintf(temp, "%02x ", (*ptr & 0xff ) ); memcpy(hex.shex + point , temp, 3); hex.point ++; } if( hex.point ) printf("%s: %s | %s |\n", hex.scop, hex.shex, hex.sstr); printf("%25s------- End ------- \n", ""); return 0 ; }
