Body
<p>I am trying the listing directories example from K&R section 8.6, but when testing the code it, says "can't access" for every single file in the directory. It is because it's designed for Unix? Below is what I think the code should look like when pieced together, what am I missing? <strong>ADD:How do I fix this code to make it work?</strong></p> <pre><code>#include <stdio.h> #include <string.h> #include <unistd.h> #include <sys/types.h> #include <sys/stat.h> #include "dirent.h" #include <sys/dir.h> #define NAME_MAX 14 typedef struct { long ino; char name[NAME_MAX+1]; } Dirent; void fsize(char *); /* print file sizes */ main(int argc, char **argv) { if (argc == 1) fsize("."); else while (--argc > 0) fsize(*++argv); return 0; } void dirwalk(char *, void (*fcn)(char *)); /* fsize: print size of file "name" */ void fsize(char *name) { struct stat stbuf; if (stat(name, &stbuf) == -1) { fprintf(stderr, "fsize: can't access %s\n", name); return; } if ((stbuf.st_mode & S_IFMT) == S_IFDIR) dirwalk(name, fsize); printf("%81d %s\n", stbuf.st_size, name); } #define MAX_PATH 1024 /* dirwalk: apply fn to all files in dir */ void dirwalk(char *dir, void (*fcn)(char *)) { char name[MAX_PATH]; Dirent *dp; DIR *dfd; if ((dfd = opendir(dir)) == NULL) { fprintf(stderr, "dirwalk: can't open %s\n", dir); return; } while ((dp = readdir(dfd)) != NULL) { if (strcmp(dp->name, ".") == 0 || strcmp(dp->name, "..") == 0) continue; if (strlen(dir)+strlen(dp->name)+2 > sizeof(name)) fprintf(stderr, "dirwalk: name %s/%s too long\n", dir, dp->name); else { sprintf(name, "%s/%s", dir, dp->name); (*fcn)(name); } } closedir(dfd); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
