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 single 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_STRING, GD_UNKNOWN.

       Passing GD_NULL or GD_UNKNOWN to this macro will return zero.  Passing GD_STRING will return sizeof(const
       char*).  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 return 8.

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


HISTORY
       The GD_SIZE() macro appeared in GetData-0.3.0
