linux C获取给定路径的父目录

 

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <libgen.h>

int main(int argc, char*argv[])
{
    char *dirc, *basec, *bname, *dname;
    char *path = "/data1/peifx/nfs/coredumpBx11";

    dirc = strdup(path);
    basec = strdup(path);
    dname = dirname(dirc);
    bname = basename(basec);

    printf(" path:%s\n dirc:%s\n basec:%s\n dname:%s\n bname:%s\n", path, dirc, basec, dname, bname);

    return 0;
}

 

注意：
使用dirname(),basename()时，要拷贝一份源路径。会修改原路径字符串。
