20,175,325 achieve mypwd (elected to do, points)

First, the subject content:

Learning pwd command 1
2 Study pwd achieve desired system call (man -k; grep), write pseudocode
3 mypwd achieved
. 4 Test mypwd

Second, the steps of:

Function: View the "current working directory" full path
using the man command pwd

pwd implementation

Study pwd achieve desired system call (man -k; grep), write pseudocode
man -k current directory

man getcwd

Implementation and testing mypwd

Third, the test code:

int get_name(int inode,char path[][BUFFERSIZE],int h)  
{   
    DIR *dir;  
    struct dirent *dir2;  
    if((dir = opendir(".")) == NULL){  
        perror(".");  
        exit(-1);  
    }   
    while((dir2 = readdir(dir)) != NULL)  
    {  
        if(dir2->d_ino == inode)
           { 
            strcpy(path[h],dir2->d_name); 
            break;
            } 
              
    }  
    h = h+1;
    return h; 
}
