我原来的程序是1.0.1，现在的程序是1.2的，
原来的userec是这样的
struct userec {                 /* Structure used to hold information in */
    char userid[IDLEN + 2];     /* PASSFILE */
    char flags[2];
    time_t firstlogin;
    char lasthost[16];
    unsigned int numlogins;
    unsigned int numposts;
#ifdef CONV_PASS
    char passwd[OLDPASSLEN];
        char unused_padding[2];
#endif
    char username[NAMELEN];
    unsigned int club_read_rights[MAXCLUB>>5];
    unsigned int club_write_rights[MAXCLUB>>5];
    unsigned char md5passwd[MD5PASSLEN];
    unsigned userlevel;
    time_t lastlogin;
    time_t stay;
    int signature;
    unsigned int userdefine;
    time_t notedate;
    int noteline;
    int notemode;
    time_t exittime;
        /* 生日数据转移到 userdata 结构中 */
    unsigned int usedspace;     /* used space of user's mailbox, in bytes */
};


转化程序如下：


#include "bbs.h"
#include "stdio.h"

struct userec1 {                /* Structure used to hold information in */
        char userid[IDLEN + 2];     /* PASSFILE */
        char flags[2];
        time_t firstlogin;
        char lasthost[16];
        unsigned int numlogins;
        unsigned int numposts;
#ifdef CONV_PASS
        char passwd[OLDPASSLEN];
        char unused_padding[2];
#endif
        char username[NAMELEN];
        unsigned int club_read_rights[MAXCLUB>>5];
        unsigned int club_write_rights[MAXCLUB>>5];
        unsigned char md5passwd[MD5PASSLEN];
        unsigned userlevel;
        time_t lastlogin;
        time_t stay;
        int signature;
        unsigned int userdefine;
        time_t notedate;
        int noteline;
        int notemode;
        time_t exittime;
        /* 生日数据转移到 userdata 结构中 */
        unsigned int usedspace;     /* used space of user's mailbox, in bytes */
};

struct userec2 {                /* Structure used to hold information in */
        char userid[IDLEN + 2];     /* PASSFILE */
        char flags;                 /*一些标志，戒网，版面排序之类的 */
        unsigned char title;        /*用户级别 */
        time_t firstlogin;
        char lasthost[16];
        unsigned int numlogins;
        unsigned int numposts;
#ifdef CONV_PASS
        char passwd[OLDPASSLEN];
        char unused_padding[2];
#endif
        char username[NAMELEN];
        unsigned int club_read_rights[MAXCLUB >> 5];
        unsigned int club_write_rights[MAXCLUB >> 5];
        unsigned char md5passwd[MD5PASSLEN];
        unsigned userlevel;
        time_t lastlogin;
        time_t stay;
        int signature;
        unsigned int userdefine[2];
        time_t notedate;
        int noteline;
        int notemode;
        time_t exittime;
        /*
        *      * 生日数据转移到 userdata 结构中
        *           */
        unsigned int usedspace;     /* used space of user's mailbox, in bytes */
#ifdef HAVE_USERMONEY
        int money;
        int score;
        char unused[20];
#endif
};

int main(int argc, char *argv[])
{
        FILE *fp, *fp2;
        struct userec1 bh;
        struct userec2 bhnew;

        int i;

        if (argc != 3) {
                printf("usage: convert Old_PASSWDS_FILE New_PASSWDS_FILE\n");
                exit(0);
        }
        if ((fp = fopen(argv[2], "r")) != NULL) {
                printf("NEW FILE exist!");
                fclose(fp);
                exit(0);
        }
        if ((fp = fopen(argv[1], "r")) == NULL) {
                printf("open .BOARDS file failed!");
                exit(0);
        }

        if ((fp2 = fopen(argv[2], "w")) == NULL) {
                printf("cant create newboards file!");
                exit(0);
        }

        while (fread(&bh, sizeof(struct userec1), 1, fp)) {
                memset(&bhnew, 0, sizeof(struct userec2));
                memcpy(&bhnew, &bh, sizeof(struct userec1));
                bhnew.userdefine[1] = -1;
                bhnew.notedate = bh.notedate;
                bhnew.noteline = bh.noteline;
                bhnew.notemode = bh.notemode;
                bhnew.exittime = bh.exittime;
                bhnew.usedspace = bh.usedspace;
                fwrite(&bhnew, sizeof(struct userec2), 1, fp2);
        }

        fclose(fp2);
        fclose(fp);
        return 0;
}
