NAME¶

SDL_GetWindowBordersSize - Get the size of a window's borders (decorations) around the client area.

SYNOPSIS¶

#include "SDL3/SDL.h"

int SDL_GetWindowBordersSize(SDL_Window *window, int *top, int *left, int *bottom, int *right);

DESCRIPTION¶

Note: If this function fails (returns -1), the size values will be initialized to 0, 0, 0, 0 (if a non-NULL pointer is provided), as if the window in question was borderless.

Note: This function may fail on systems where the window has not yet been decorated by the display server (for example, immediately after calling

SDL_CreateWindow ). It is recommended that you wait at least until the window has been presented and composited, so that the window system has a chance to decorate the window and provide the border dimensions to SDL.

This function also returns -1 if getting the information is not supported.

FUNCTION PARAMETERS¶

window

the window to query the size values of the border (decorations) from

top

pointer to variable for storing the size of the top border; NULL is permitted

left

pointer to variable for storing the size of the left border; NULL is permitted

bottom

pointer to variable for storing the size of the bottom border; NULL is permitted

right

pointer to variable for storing the size of the right border; NULL is permitted

RETURN VALUE¶

Returns 0 on success or a negative error code on failure; call

SDL_GetError () for more information.

AVAILABILITY¶

This function is available since SDL 3.0.0.
