This header is available in C99 and C11.

The header <stdint.h> defines several type aliases for integer types that are characterized by their widths.

Types of the form uintw_t, such as uint32_t, are unsigned types of exactly w value bits. intw_t are signed equivalents, so they have w−1 value bits and one sign bit. While most platforms support such types in hardware, some do not, so these types are optional. You can detect their existence by checking whether the macro UINTw_MAX or INTw_MAX is defined.

Other types are guaranteed to exist. Those of the form uint_leastw_t are the smallest types with at least w value bits, but they could have more. Those of the form uint_fastw_t are likely to be fastest types with at least w value bits. Macros of the form UINTw_C can be used to create constants of these types. They have signed equivalents, and all come with macros of the forms UINTw_MAX, INTw_MIN and INTw_MAX to specify their ranges.

typedef names matching ^(u?)int.*_t$, might be added to <stdint.h>. Macros with names matching ^(U?)INT.*(_MIN|_MAX|_C)$ might be added to <stdint.h>.

The header <inttypes.h> includes the header <stdint.h>, and additionally defines macros for using these types with printf and scanf.

Macros with names matching ^(PRI|SCN)[a-zX] might be added to <inttypes.h>. This will allow for new abstract integer types.
