Параметры
nIndex
Specifies the line number to retrieve from a multiple-line edit control. Line numbers are zero-based; a value of 0 specifies the first line. This parameter is ignored by a single-line edit control.lpszBuffer
Points to the buffer that receives a copy of the line. The first word of the buffer must specify the maximum number of bytes that can be copied to the buffer.nMaxLength
Specifies the maximum number of bytes that can be copied to the buffer. GetLine places this value in the first word of lpszBuffer before making the call to Windows.
Возвращаемое значение
The number of bytes actually copied. The return value is 0 if the line number specified by nIndex is greater than the number of lines in the edit control.
Заметки
The copied line does not contain a null-termination character.
