One-byte integers
The DataBlade
API supports
the following data types for one-byte integer values.
| DataBlade API one-byte integer | Description |
|---|---|
| mi_sint1 | Signed one-byte (eight bits) value |
| mi_int1 | Unsigned one-byte (eight bits) value |
To hold unsigned one-byte integers, you can also use the mi_unsigned_char1 data
type.
Tip: The one-byte integer data types have names that
are not consistent with those of other integer data types. The mi_int1 data
type is for an unsigned one-byte integer while the mi_smallint, mi_integer,
and mi_int8 data types are for the signed version of the two-,
four-, and eight-byte integers, respectively. Use the mi_sint1 data
type to hold a signed one-byte integer value.
The DataBlade API ensures that these integer data types are one byte on all computer architectures. There is no corresponding SQL data type for one-byte integers.
Values of the mi_int1 and mi_sint1 data types can fit into an MI_DATUM structure. They can be passed by value within C user-defined routines (UDRs).
All data types, including mi_int1 and mi_sint1, must be passed by reference within client LIBMI applications.
