1.
WIN32_FIND_DATA m_data;
HANDLE hFile;
hFile=FindFirstFile(filename,&m_data)
if(hFile==INVALID_HANDLE_VALUE) //file not found
Make sure you close the handle if the file is found.
FindClose(hFile);
2.
You can use SHGetFileInfo()
The prototype of the function is as follows:
DWORD_PTR SHGetFileInfo(
LPCTSTR pszPath,
DWORD dwFileAttributes,
SHFILEINFO *psfi,
UINT cbFileInfo,
UINT uFlags
);
3.
PathFileExists
4. 加一个标准c库函数
Example
/* ACCESS.C: This example uses _access to check the
* file named "ACCESS.C" to see if it exists and if
* writing is allowed.
*/
#include <io.h>
#include <stdio.h>
#include <stdlib.h>
void main( void )
{
/* Check for existence */
if( (_access( "ACCESS.C", 0 )) != -1 )
{
printf( "File ACCESS.C exists\n" );
/* Check for write permission */
if( (_access( "ACCESS.C", 2 )) != -1 )
printf( "File ACCESS.C has write permission\n" );
}
}
