PutDouble


The PutDouble method writes double precision (64 bit) floating point number sequence to file and returns number of elements actually written. File position is moved forward by the number of bytes written.
C++
long PutDouble(
  double *DoubleBuffer,            // buffer that contains data
  long NumberOfElements,           // number of elements to write
  long FilePosition = -1           // position of data in file
);
BASIC
PutDouble(
  DoubleBuffer As Variant,         // variant that contains data
  NumberOfElements As Long = -1,   // number of elements to write
  FilePosition As Long = -1        // position of data in file
) As Long

Parameters

DoubleBuffer
C++
Pointer to buffer that contains data.
BASIC
Variant that contains data.
Variant must be of Double data type; it can be either single variable or one-dimensional array.
NumberOfElements
Number of elements in data sequence to write.
BASIC
If this parameter is -1 length of sequence is determined by the size of DoubleBuffer.
FilePosition
Position in file to write data at.
If this parameter is -1 data is written at current file position.

Return Values

If the method succeeds, the return value is the number of elements actually written.
If the method fails, the return value is failure code and error code is set. Call GetError to get error code.

Remarks

BASIC
DoubleBuffer can be either single variable of type Double or one-dimensional Double array, depending on how many elements are to be written. If only one element is written, DoubleBuffer can be a single variable, if more than one element is to be written it must be a one-dimensional array.
