CopyFile The CopyFile function copies an existing file to a new file. BOOL CopyFile( LPCTSTR lpExistingFileName, // pointer to name of an existing file LPCTSTR lpNewFileName, // pointer to filename to copy to BOOL bFailIfExists // flag for operation if file exists );
Parameters lpExistingFileName Pointer to a null-terminated string that specifies the name of an existing file. lpNewFileName Pointer to a null-terminated string that specifies the name of the new file. bFailIfExists Specifies how this operation is to proceed if a file of the same name as that specified by lpNewFileName already exists. If this parameter is TRUE and the new file already exists, the function fails. If this parameter is FALSE and the new file already exists, the function overwrites the existing file and succeeds. Return Values If the function succeeds, the return value is nonzero.If the function fails, the return value is zero. To get extended error information, call GetLastError. Res Security attributes for the existing file are not copied to the new file.

The CopyFile function copies an existing file to a new file. BOOL CopyFile(
LPCTSTR lpExistingFileName,
// pointer to name of an existing file
LPCTSTR lpNewFileName, // pointer to filename to copy to
BOOL bFailIfExists // flag for operation if file exists
);
Parameters
lpExistingFileName
Pointer to a null-terminated string that specifies the name of an existing file.
lpNewFileName
Pointer to a null-terminated string that specifies the name of the new file.
bFailIfExists
Specifies how this operation is to proceed if a file of the same name as that specified by lpNewFileName already exists. If this parameter is TRUE and the new file already exists, the function fails. If this parameter is FALSE and the new file already exists, the function overwrites the existing file and succeeds.
Return Values
If the function succeeds, the return value is nonzero.If the function fails, the return value is zero. To get extended error information, call GetLastError. Res
Security attributes for the existing file are not copied to the new file.
LPCTSTR lpExistingFileName,
// pointer to name of an existing file
LPCTSTR lpNewFileName, // pointer to filename to copy to
BOOL bFailIfExists // flag for operation if file exists
);move file;
MoveFile()
例如,
要将c:\abc.txt 拷到 D:\ 下面!
CopyFile( “c:\abc.txt” , d:\abc.txt ,true);
true表示覆盖已有文件!
