sl@0: // Description:
sl@0: // Name        : wfindfirst.cpp
sl@0: // Part of     : libc library
sl@0: // The _wfindfirst function provides information about the first 
sl@0: // instance of a file name that matches the file specified in the 
sl@0: // filespec argument. Any wildcard combination supported by the host 
sl@0: // operating system can be used in filespec. 
sl@0: // File information is returned in a _wfinddata_t structure, defined in wchar.h
sl@0: // FUNCTIONS
sl@0: // _wfindfirst, _wfindnext, _findclose
sl@0: // INDEX
sl@0: // _wfindfirst
sl@0: // _wfindnext
sl@0: // _findclose
sl@0: // ANSI_SYNOPSIS
sl@0: // #include <wchar.h>
sl@0: // int _wfindnext(intptr_t, struct _wfinddata_t *); 
sl@0: // intptr_t wfindfirst(const wchar_t* , struct _wfinddata_t* );
sl@0: // int findclose( intptr_t handle);
sl@0: // The _wfindfirst function provides information about the first 
sl@0: // instance of a file name that matches the file specified in the 
sl@0: // filespec argument. Any wildcard combination supported by the host 
sl@0: // operating system can be used in filespec. 
sl@0: // File information is returned in a _wfinddata_t structure, defined in wchar.h
sl@0: // wfindnext find the next name, if any, that matches the filespec argument 
sl@0: // in a previous call to _findfirst, and then alter the fileinfo structure 
sl@0: // contents accordingly.
sl@0: // _findclose  
sl@0: // Closes the specified search handle and releases associated resources.
sl@0: // RETURNS
sl@0: // _findclose
sl@0: // If successful, returns 0. Otherwise, it returns –1 and sets errno to ENOENT
sl@0: // _wfindnext
sl@0: // If successful, returns 0. Otherwise, returns –1 and sets errno to a value indicating the nature of the failure. Possible error codes are shown below. 
sl@0: // EINVAL
sl@0: // Invalid parameter: fileinfo was NULL. Or, the operating system returned an unexpected error.
sl@0: // ENOENT
sl@0: // No more matching files could be found.
sl@0: // _wfindfirst
sl@0: // If successful, _findfirst returns a unique search handle identifying the file or group of files
sl@0: // matching the filespec specification, which can be used in a subsequent call to _findnext or to 
sl@0: // _findclose. Otherwise, _findfirst returns –1 and sets errno to one of the following values.
sl@0: // EINVAL
sl@0: // Invalid parameter: filespec or fileinfo was NULL. Or, the operating system returned an unexpected error.
sl@0: // ENOENT
sl@0: // File specification that could not be matched.
sl@0: // ENOMEM
sl@0: // Not enough memory or the file name given was greater than MAX_PATH.
sl@0: // EINVAL
sl@0: // Invalid file name specification.
