'''glDepthMask:''' enable or disable writing into the depth buffer

== Function Definition ==

  void '''glDepthMask'''(GLboolean {{param|flag}});

; flag
: Specifies whether the depth buffer is enabled for writing. If {{param|flag}} is {{enum|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 {{param|flag}} is {{enum|GL_FALSE}}, depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth buffer writing is enabled.

== Associated Gets ==

{{apifunc|glGet}} with argument {{enum|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 {{enum|GL_ALWAYS}} (see {{apifunc|glDepthFunc}}).
