'''_glDepthMask''' specifies whether the depth buffer is enabled for writing. If {{Parameter|flag}} is {{KW|_GL_FALSE}}, depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth buffer writing is enabled.

|
{{PageNotes}}
|
|
|
|
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 {{KW|_GL_ALWAYS}} (see {{KW|_glDepthFunc}}).
