Linux cli command int16_ttype

➡ A Linux man page (short for manual page) is a form of software documentation found on Linux and Unix-like operating systems. This man-page explains the command int16_ttype and provides detailed information about the command int16_ttype, system calls, library functions, and other aspects of the system, including usage, options, and examples of _. You can access this man page by typing man followed by the int16_ttype.

DESCRIPTION

intN*_t* are signed integer types of a fixed width of exactly N bits, N being the value specified in its type name. They are be capable of storing values in the range [INTN**_MIN**, INTN**_MAX**], substituting N by the appropriate number.

uintN*_t* are unsigned integer types of a fixed width of exactly N bits, N being the value specified in its type name. They are capable of storing values in the range [0, UINTN**_MAX**], substituting N by the appropriate number.

According to POSIX, [u]int8_t, [u]int16_t, and [u]int32_t are required; [u]int64_t are only required in implementations that provide integer types with width 64; and all other types of this form are optional.

The macros [U]INTN**_WIDTH** expand to the width in bits of these types (N).

The macros [U]INTN**_MAX** expand to the maximum value that these types can hold.

The macros INTN**_MIN** expand to the minimum value that these types can hold.

The macros [U]INTN**_C**() expand their argument to an integer constant of type [u]intN*_t*.

The length modifiers for the [u]intN*_t* types for the printf(3) family of functions are expanded by macros of the forms PRIdN, PRIiN, PRIuN, and PRIxN (defined in <inttypes.h>); resulting for example in %“PRId64” or %“PRIi64” for printing int64_t values. The length modifiers for the [u]intN*_t* types for the scanf(3) family of functions are expanded by macros of the forms SCNdN, SCNiN, SCNuN, and SCNxN, (defined in <inttypes.h>); resulting for example in %“SCNu8” or %“SCNx8” for scanning uint8_t values.

STANDARDS

C11, POSIX.1-2008.

HISTORY

C99, POSIX.1-2001.

The [U]INTN**_WIDTH** macros were added in C23.

NOTES

The following header also provides these types: <inttypes.h>. <arpa/inet.h> also provides uint16_t and uint32_t.
