GD_SIZE(3)			    GETDATA			    GD_SIZE(3)

NAME
       GD_SIZE — report the size of a GetData data sample

SYNOPSIS
       #include <getdata.h>

       int GD_SIZE(gd_type_t type);

DESCRIPTION
       The  GD_SIZE() preprocessor macro returns the size (in bytes) of a sin‐
       gle sample of data of the type specified by type, which should  be  one
       of the symbols

	      GD_NULL, GD_UINT8, GD_INT8, GD_UINT16, GD_INT16, GD_UINT32,
	      GD_INT32, GD_FLOAT32, GD_FLOAT64, GD_COMPLEX64, GD_COMPLEX128,
	      GD_UNKNOWN.

       Passing	GD_NULL or GD_UNKNOWN to this macro will return zero.  For the
       other types, the value returned is simply the bit-size encoded  in  the
       type  symbol divided by eight, so, e.g., GD_SIZE(GD_COMPLEX64) will re‐
       turn 8.

       No error checking is performed on type: behaviour resulting from	 pass‐
       ing  something other than the symbols listed above to this macro is un‐
       specified.  See gd_getdata(3) for the meaning of the above symbols.
