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
