Integer Data Types

CDF_BYTE

1-byte, signed integer.

CDF_INT1

1-byte, signed integer.

CDF_UINT1

1-byte, unsigned integer.

CDF_INT2

2-byte, signed integer.

CDF_UINT2

2-byte, unsigned integer.

CDF_INT4

4-byte, signed integer.

CDF_UINT4

4-byte, unsigned integer.

NOTE: When using C on a DEC Alpha running OSF/1, keep in mind that a long is 8 bytes and that an int is 4 bytes. Use an int with the data types CDF_INT4 and CDF_UINT4 rather than a long. NOTE: When using C on an IBM PC (MS-DOS ), keep in mind that an int is 2 bytes and that a long is 4 bytes. Use a long with the data types CDF_INT4 and CDF_UINT4 rather than an int. cdfsupport@nssdca.gsfc.nasa.gov
