int findnext(struct ffblk *ffblk );
int _wfindnext(struct _wffblk *ffblk );
Description
Continues findfirst search.
findnext is used to fetch subsequent files that match the pathname given in findfirst. ffblk is the same block filled in by the findfirst call. This block contains necessary information for continuing the search. One file name for each call to findnext will be returned until no more files are found in the directory matching the pathname.
Return Value
findnext returns 0 on successfully finding a file matching the search pathname. When no more files can be found or if there is an error in the file name
-1 is returned
errno is set to
|
ENOENT |
Path or file name not found |
_doserrno is set to one of the following values:
|
ENMFILE |
No more files |
|
ENOENT |
Path or file name not found |
Example
#include <stdio.h>
#include <dir.h>
void print_dir(wchar_t* dir_name)
{
/* Open a find stream (_wfinddata_t and a find handle) */
_wffblk find_data;
int done;
done = _wfindfirst(dir_name, &find_data, 0);
/* Scan all files that mach */
while (!done)
{
printf("%ls\n", find_data.ff_name);
done = _wfindnext(&find_data);
}
/* Close the find handle */
_wfindclose(&find_data);
}
