Standard buffer size constants.

Macro Definition Documentation

BUFFER_SIZE_HUGE

#define BUFFER_SIZE_HUGE   16384

#include <buffer_sizes.h>

Huge buffer size (16kb)

Used for huge buffers like stack traces and other system messages.

Definition at line 76 of file buffer_sizes.h.

BUFFER_SIZE_LARGE

#define BUFFER_SIZE_LARGE   1024

#include <buffer_sizes.h>

Large buffer size (1024 bytes)

Used for longer strings, full paths, and larger temporary buffers.

Definition at line 40 of file buffer_sizes.h.

BUFFER_SIZE_MEDIUM

#define BUFFER_SIZE_MEDIUM   512

#include <buffer_sizes.h>

Medium buffer size (512 bytes)

Used for medium-length strings, paths, and intermediate buffers.

Definition at line 31 of file buffer_sizes.h.

BUFFER_SIZE_SMALL

#define BUFFER_SIZE_SMALL   256

#include <buffer_sizes.h>

Small buffer size (256 bytes)

Used for short strings, error messages, and small temporary buffers.

Definition at line 22 of file buffer_sizes.h.

BUFFER_SIZE_XLARGE

#define BUFFER_SIZE_XLARGE   2048

#include <buffer_sizes.h>

Extra large buffer size (2048 bytes)

Used for very long strings, multiple paths, and large temporary buffers.

Definition at line 49 of file buffer_sizes.h.

BUFFER_SIZE_XXLARGE

#define BUFFER_SIZE_XXLARGE   4096

#include <buffer_sizes.h>

Extra extra large buffer size (4096 bytes)

Used for maximum-length paths and very large temporary buffers.

Definition at line 58 of file buffer_sizes.h.

BUFFER_SIZE_XXXLARGE

#define BUFFER_SIZE_XXXLARGE   8192

#include <buffer_sizes.h>

Extra extra extra large buffer size (8192 bytes)

Used for extremely large buffers like exception messages and stack traces.

Definition at line 67 of file buffer_sizes.h.

BYTES_PER_RGB_PIXEL

#define BYTES_PER_RGB_PIXEL   3

#include <buffer_sizes.h>

Bytes per pixel in RGB24 format (red + green + blue)

Definition at line 87 of file buffer_sizes.h.

IMAGE_FRAME_HEADER_SIZE_LEGACY

#define IMAGE_FRAME_HEADER_SIZE_LEGACY   8

#include <buffer_sizes.h>

Legacy image frame header size (width:4 + height:4)

Used for backward compatibility with older frame format.

Definition at line 96 of file buffer_sizes.h.

IMAGE_FRAME_HEADER_SIZE_NEW

#define IMAGE_FRAME_HEADER_SIZE_NEW   16

#include <buffer_sizes.h>

New image frame header size (width:4 + height:4 + compressed:4 + size:4)

Used for new compressed frame format with compression flag and data size.

Definition at line 105 of file buffer_sizes.h.

MAX_FRAME_BUFFER_SIZE

#define MAX_FRAME_BUFFER_SIZE   (2 * 1024 * 1024)

#include <buffer_sizes.h>

Maximum frame buffer size including headers and compression.

Used as a practical limit to prevent memory exhaustion from oversized frames. This is larger than typical compressed frames but smaller than uncompressed RGB.

Definition at line 143 of file buffer_sizes.h.

MAX_FRAME_HEIGHT

#define MAX_FRAME_HEIGHT   1080

#include <buffer_sizes.h>

Maximum reasonable frame height (prevents memory exhaustion)

Definition at line 119 of file buffer_sizes.h.

MAX_FRAME_PIXELS

#define MAX_FRAME_PIXELS   (MAX_FRAME_WIDTH * MAX_FRAME_HEIGHT)

#include <buffer_sizes.h>

Maximum total frame pixels (width * height)

Definition at line 126 of file buffer_sizes.h.

MAX_FRAME_RGB_SIZE

#define MAX_FRAME_RGB_SIZE   (MAX_FRAME_PIXELS * BYTES_PER_RGB_PIXEL)

#include <buffer_sizes.h>

Maximum RGB buffer size (MAX_FRAME_PIXELS * BYTES_PER_RGB_PIXEL)

Definition at line 133 of file buffer_sizes.h.

MAX_FRAME_WIDTH

#define MAX_FRAME_WIDTH   1920

#include <buffer_sizes.h>

Maximum reasonable frame width (prevents memory exhaustion)

Definition at line 112 of file buffer_sizes.h.
