NAME

xcb_shm_attach_fd - Create a shared memory segment

SYNOPSIS

#include <xcb/shm.h>

Request function

xcb_void_cookie_t xcb_shm_attach_fd (xcb_connection_t * conn , xcb_shm_seg_t shmseg , int32_t shm_fd , uint8_t read_only );

REQUEST ARGUMENTS


	conn		The XCB connection to X11.
	shmseg		A shared memory segment ID created with xcb_generate_id().
	shm_fd		The file descriptor the server should mmap().
	read_only		True if the segment shall be mapped read only by the X11 server, otherwise false.

DESCRIPTION

Create a shared memory segment. The file descriptor will be mapped at offset zero, and the size will be obtained using fstat(). A zero size will result in a Value error.

RETURN VALUE

Returns an xcb_void_cookie_t . Errors (if any) have to be handled in the event loop.

If you want to handle errors directly with xcb_request_check instead, use xcb_shm_attach_fd_checked . See xcb-requests(3) for details.

ERRORS

This request does never generate any errors.
