**_glDepthMask:** enable or disable writing into the depth buffer
|
|
|

|
|
## Syntax
|
|
|
|
|
|
> : SUB _glDepthMask (BYVAL flag AS _UNSIGNED _BYTE)
|
|
> : void **_glDepthMask**(GLboolean flag);
|
|
|
|
|
|
; flag
|
|
> Specifies whether the depth buffer is enabled for writing. If flag is [_GL_FALSE](_GL_FALSE), depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth buffer writing is enabled.

## Description
|
|
|
|
|
|
**_glDepthMask** specifies whether the depth buffer is enabled for writing. If flag is [_GL_FALSE](_GL_FALSE), depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth buffer writing is enabled.
|
|
|
|
|
|
## Use With
|
|
|
|
|
|
[_glGet](_glGet) with argument [_GL_DEPTH_WRITEMASK](_GL_DEPTH_WRITEMASK)
|
|
|
|
|
|
## Notes
|
|
|
|
|
|
Even if the depth buffer exists and the depth mask is non-zero, the depth buffer is not updated if the depth test is disabled. In order to unconditionally write to the depth buffer, the depth test should be enabled and set to [_GL_ALWAYS](_GL_ALWAYS) (see [_glDepthFunc](_glDepthFunc)).
