用法：merge oldbrd newbrd
将oldbrd合并到newbrd中，名称区分大小写
比如 merge sysop syssecurity，将sysop的文章合并到syssecurity

#include "bbs.h"

int dashf(char *fname){
        struct stat st;
        return(stat(fname, &st) == 0 && S_ISREG(st.st_mode));
}

void merge(char *brd1, char *brd2, char *fname){
        int fdr, fdw, size, now;
        char buf[STRLEN], buf2[STRLEN];
        struct fileheader fh;

        size = sizeof(struct fileheader);
        sprintf(buf, "%s/boards/%s/%s", BBSHOME, brd1, fname);
        fdr = open(buf, O_RDONLY);
        sprintf(buf, "%s/boards/%s/%s", BBSHOME, brd2, fname);
        fdw = open(buf, O_WRONLY | O_CREAT, 0644);
        if(fdr == -1 || fdw == -1)
                return;
        flock(fdw, LOCK_EX);
        lseek(fdw, 0, SEEK_END);
        while(read(fdr, &fh, size) == size){
                now = atoi(fh.filename + 2);
                do{
                        buf[0] = fh.filename[0];
                        buf[1] = '\0';
                        sprintf(buf2, "%s.%d.A", buf, now);
                        sprintf(buf, "%s/boards/%s/%s", BBSHOME, brd2, buf2);
                        now++;
                }while(dashf(buf));
                sprintf(buf2, "%s/boards/%s/%s", BBSHOME, brd1, fh.filename);
                link(buf2, buf);
                buf[0] = fh.filename[0];
                buf[1] = '\0';
                sprintf(fh.filename, "%s.%d.A", buf, now - 1);
                write(fdw, &fh, size);
        }
        flock(fdw, LOCK_UN);
        close(fdw);
        close(fdr);
}
