如何在SDK中作文件的读写操作,最好具体一点.

[hfqian]

从标准C开始就提供了文件操作的接口，可以直接使用（只要你用得是ANSI C）。fopen、fread、fclose等等

HANDLE hFile;

HANDLE hAppend;

DWORD dwBytesRead, dwBytesWritten, dwPos;

char buff[4096];

// Open the existing file.

hFile = CreateFile("ONE.TXT", // open ONE.TXT
GENERIC_READ, // open for reading
0, // do not share
NULL, // no security
OPEN_EXISTING, // existing file only
FILE_ATTRIBUTE_NORMAL, // normal file
NULL); // no attr. template

if (hFile == INVALID_HANDLE_VALUE)
{
ErrorHandler("Could not open ONE."); // process error
}

// Open the existing file, or if the file does not exist,
// create a new file.

hAppend = CreateFile("TWO.TXT", // open TWO.TXT
GENERIC_WRITE, // open for writing
0, // do not share
NULL, // no security
OPEN_ALWAYS, // open or create
FILE_ATTRIBUTE_NORMAL, // normal file
NULL); // no attr. template

if (hAppend == INVALID_HANDLE_VALUE)
{
ErrorHandler("Could not open TWO."); // process error
}

// Append the first file to the end of the second file.
// Lock the second file to prevent another process from
// accessing it while writing to it. Unlock the
// file when writing is finished.

do
{
if (ReadFile(hFile, buff, 4096, &dwBytesRead, NULL))
{
dwPos = SetFilePointer(hAppend, 0, NULL, FILE_END);
LockFile(hAppend, dwPos, 0, dwPos + dwBytesRead, 0);
WriteFile(hAppend, buff, dwBytesRead,
&dwBytesWritten, NULL);
UnlockFile(hAppend, dwPos, 0, dwPos + dwBytesRead, 0);
}
} while (dwBytesRead == 4096);

// Close both files.

CloseHandle(hFile);
CloseHandle(hAppend);

那方面的？
_read file or rend *.ini?

ReadFile
WriteFile
都是API
