The limits defined by <inttypes.h> are constants that specify the minimum and maximum values of various integer types. This includes minimum and maximum values for each of the fixed-width types such as INT8_MIN,…, INT64_MIN, INT8_MAX,…, INT64_MAX, and their unsigned counterparts.

The <inttypes.h> file also provides the minimum and maximum for each of the least-sized types. These include INT_LEAST8_MIN,…, INT_LEAST64_MIN, INT_LEAST8_MAX,…, INT_LEAST64_MAX, as well as their unsigned counterparts.

Finally, <inttypes.h> defines the minimum and maximum value of the largest supported integer types. These include INTMAX_MIN and INTMAX_MAX and their corresponding unsigned versions.
