astPutColumnData
-
Retrieve all the data values stored in a column
- Description:
- This function
copies data values from a supplied buffer into a named column. The
first element in the buffer becomes the first element in the first
row of the column. If the buffer does not completely fill the
column, then any trailing rows are filled with null values.
- Synopsis:
- void astPutColumnData( AstFitsTable
this, const char
column,
int clen, size_t size, void
coldata )
- Parameters:
-
this
-
Pointer to the FitsTable.
-
column
-
The character string holding the name of the column. Trailing
spaces are ignored.
-
clen
-
If the column holds character strings, then this must be set to
the length of each fixed length string in the supplied array.
This is often determined by the appropriate TFORMn keyword in
the binary table header. The supplied value is ignored if the
column does not hold character data.
-
size
-
The size of the
"coldata"
array, in bytes. This should be an integer multiple of the
number of bytes needed to hold the full vector value stored in a
single cell of the column. An error is reported if this is not
the case.
-
coldata
-
A pointer to an
area of memory holding the data to copy into the column. The values
should be stored in row order. If the column holds non-scalar values,
the elements of each value should be stored in "Fortran" order. No
data type conversion is performed.
