A - pointer is returned to identify the directory stream in sub- - sequent operations. The pointer NULL is returned if the - specified filename can not be accessed, or if insufficient - memory is available to open the directory file. - - The readdir routine returns a pointer to the next directory - entry. It returns NULL upon reaching the end of the direc- - tory or on detecting an invalid seekdir operation. The - readdir routine uses the getdirentries system call to read - directories. Since the readdir routine returns NULL upon - reaching the end of the directory or on detecting an error, - an application which wishes to detect the difference must - set errno to 0 prior to calling readdir. - - The telldir routine returns the current location associated - with the named directory stream. Values returned by telldir - are good only for the lifetime of the DIR pointer from which - they are derived. If the directory is closed and then reo- - pened, the telldir value may be invalidated due to - undetected directory compaction. - - The seekdir routine sets the position of the next readdir - operation on the directory stream. Only values returned by - telldir should be used with seekdir. - - The rewinddir routine resets the position of the named - directory stream to the beginning of the directory. - - The closedir routine closes the named directory stream and - returns a value of 0 if successful. Otherwise, a value of -1 - is returned and errno is set to indicate the error. All - resources associated with this directory stream are - released. - -EXAMPLE - The following sample code searches a directory for the entry - name. - - len = strlen(name); - - dirp = opendir("."); - - for (dp = readdir(dirp); dp != NULL; dp = readdir(dirp)) - - if (dp->d_namlen == len && !strcmp(dp->d_name, name)) { - - closedir(dirp); - - return FOUND; - - } - - closedir(dirp); - - return NOT_FOUND; - - -SEE ALSO - close(2), getdirentries(2), lseek(2), open(2), read(2), - dir(5) -*/ |
