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
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.
