Integer Type

SANE_Int is used for variables that can take integer values in the range $-2^{32}$ to $2^{31}-1$. Its C declaration is given below.

typedef SANE_Word SANE_Int;

Note that SANE_Int is simply an alias of SANE_Word. It is therefore always legal to use the latter type in place of the former. However, for clarity, it is recommended to use SANE_Int whenever a given variable or formal argument has a fixed interpretation as an integer object.
