Header File

Category
Directory Control Routines
Prototype
long _findnext(long handle, struct _finddata_t *fileinfo);
long __wfindnext(long handle, struct _wfinddata_t *fileinfo);
Description
Finds subsequent files, if any, that match the filter argument in a previous call to _findfirst/__wfindfirst. Then, _findnext/__wfindnext updates the fileinfo structure with the necessary information for continuing the search. One file name for each call to _tfindnext is returned until no more files are found in the directory matching the pathname (filter).
The handle parameter is the search handle returned by a previous call to _findfirst. The fileinfo parameter is the file information buffer.
These functions are provided for Microsoft compatibility.
Return Value
On success, returns 0.
Otherwise, returns –1 and sets errno to:
ENOENTFile specification that could not be matched
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); }
