Detailed Description

Integer limit constants for C++ macros. One plugin serves #include <stdint.h>, #include <stddef.h> and #include <stdbool.h>. Available from LayoutEditor 20260918.

There are no functions in this binding — only named numbers. A constant is a name you write in an expression, like a variable that never changes:

if (n > INT32_MAX) { /* too large for a 32-bit signed int */ }

bool, true and false are already keywords in the macro language. They are not redefined here.

NULL is the empty pointer (integer 0). Use it when a function returns a pointer and you need to test “no object”.

Example

#include <stdint.h>
#include <stddef.h>

int main(){
    int *p = NULL;
    if (p) return 1;
    cout("INT32_MAX = ", INT32_MAX, "\n");
    cout("INT8_MIN  = ", INT8_MIN, "\n");
}

Constants

Each name is a whole number. MIN is the most negative value of that width, MAX the most positive. U…MAX is the maximum of an unsigned (never negative) integer of that width.

Member Function Documentation

int stdint.h::INT8_MIN

int stdint.h::INT8_MAX

int stdint.h::UINT8_MAX

8-bit integers (1 byte).

• INT8_MIN = -128
• INT8_MAX = 127
• UINT8_MAX = 255

Use: when you need to know whether a value fits in a byte.

int stdint.h::INT16_MIN

int stdint.h::INT16_MAX

int stdint.h::UINT16_MAX

16-bit integers (2 bytes).

• INT16_MIN = -32768
• INT16_MAX = 32767
• UINT16_MAX = 65535

int stdint.h::INT32_MIN

int stdint.h::INT32_MAX

int stdint.h::UINT32_MAX

32-bit integers (4 bytes). A normal macro int is in this range on the LayoutEditor.

• INT32_MIN = -2147483648
• INT32_MAX = 2147483647
• UINT32_MAX = 4294967295

int stdint.h::INT64_MIN

int stdint.h::INT64_MAX

int stdint.h::UINT64_MAX

64-bit integers (8 bytes).

• INT64_MIN = -9223372036854775808
• INT64_MAX = 9223372036854775807
• UINT64_MAX = 18446744073709551615

int stdint.h::SIZE_MAX

Largest value of a size (here the same magnitude as UINT64_MAX). Used in C for the type size_t (sizes of arrays and allocations).

int stdint.h::NULL

Empty pointer. Value: 0.

Example: FILE *fp = fopen(path, "r"); if (fp == NULL) { /* failed */ }

int stdint.h::__bool_true_false_are_defined

Set to 1 to signal that boolean keywords exist (they already do in the macro language). You rarely need this name in a macro.

Python: None for empty pointers; int has unlimited size. This include is for C++ macros only.
