CArchive::ReadString

Bool ReadString(CString& rString );

LPTSTR ReadString( LPTSTR lpsz, UINT nMax );
throw(
CArchiveException );

Return Value

In the version that returns Bool, TRUE if successful; FALSE otherwise.

In the version that returns an LPTSTR, a pointer to the buffer containing the text data; NULL if end-of-file was reached.

Parameters

rString

A reference to a CString that will contain the resultant string after it is read from the file associated with the CArchive object.

lpsz

Specifies a pointer to a user-supplied buffer that will receive a null-terminated text string.

nMax

Specifies the maximum number of characters to read. Should be one less than the size of the lpsz buffer.

Remarks

Call this member function to read text data into a buffer from the file associated with the CArchive object. In the version of the member function with the nMax parameter, the buffer will hold up to a limit of nMax - 1 characters. Reading is stopped by a carriage return-linefeed pair. Trailing newline characters are always removed. A null character ('\0') is appended in either case.

CArchive::Read is also available for text-mode input, but it does not terminate on a carriage return-linefeed pair.
