Directory functions

+ +

+ +OK. First things first. These functions are NOT part of the ANSI standard +library. They may not be supported on your platform. +

+ +Here is a quick summary of each function, they are listed in the order in +which you may want to execute them. + +

opendir Open a directory stream. +

readdir read the current entry in the stream. +

scandir Find an entry in a direcory. +

seekdir Jump to a directory offset. +

telldir Return the current location within the directory stream. +

rewinddir Return to the start of the directory stream. +

closedir Close a directory. + + +

+ + + + + +

+
+  Library:   dirent.h
+
+  Prototype: DIR *opendir(const char *name);
+
+             struct dirent *readdir(DIR *dir);
+
+             int scandir(const char *dir, struct dirent ***namelist,  
+                 int (*select)(const struct dirent *),
+                 int (*compar)(const void *, const void *));
+		
+	     void seekdir(DIR *dir, off_t offset);
+
+	     off_t telldir(DIR *dir);
+
+	     void rewinddir(DIR *dir);
+
+	     int closedir(DIR *dir);
+

+ +The dirent structure does not seem to be documented in the man pages, +so here it is. +

+ + + + +
+
+ + struct dirent + { + long d_ino; + off_t d_off; + unsigned short d_reclen; + char d_name[NAME_MAX+1]; + }; +
+
+ + + example program using opendir, readdir and closedir. +
