NAME

       glDepthMask - enable or disable writing into the depth buffer

C SPECIFICATION

       void glDepthMask(GLboolean flag);

PARAMETERS

       flag
           Specifies whether the depth buffer is enabled for writing. If flag is 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, depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth
       buffer writing is enabled.

ASSOCIATED GETS

       glGet() with argument 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 (see glDepthFunc()).
