GLENABLECLIENTSTATE(3G) GLENABLECLIENTSTATE(3G)

glEnableClientState, glDisableClientState - enable or disable client-side capability

C SPECIFICATION

void glEnableClientState( GLenum array )












  

  
Specifies the capability to enable. Symbolic constants
      GL_COLOR_ARRAY, GL_EDGE_FLAG_ARRAY, GL_INDEX_ARRAY,
      GL_NORMAL_ARRAY, GL_TEXTURE_COORD_ARRAY, and
      GL_VERTEX_ARRAY are accepted.








C SPECIFICATION


void glDisableClientState( GLenum array )













  

  
Specifies the capability to disable.










glEnableClientState and glDisableClientState enable
    or disable individual client-side capabilities. By default, all client-side
    capabilities are disabled. Both glEnableClientState and
    glDisableClientState take a single argument, array, which can
    assume one of the following values:



  

  
If enabled, the color array is enabled for writing and used during
      rendering when glArrayElement, glDrawArrays,
      glDrawElement, or glDrawRangeElements is called. See
      glColorPointer.

  

  
If enabled, the edge flag array is enabled for writing and used during
      rendering when glArrayElement, glDrawArrays,
      glDrawElement, or glDrawRangeElements is called. See
      glEdgeFlagPointer.

  

  
If enabled, the index array is enabled for writing and used during
      rendering when glArrayElement, glDrawArrays,
      glDrawElement, or glDrawRangeElements is called. See
      glIndexPointer.

  

  
If enabled, the normal array is enabled for writing and used during
      rendering when glArrayElement, glDrawArrays,
      glDrawElement, or glDrawRangeElements is called. See
      glNormalPointer.

  

  
If enabled, the texture coordinate array is enabled for writing and used
      during rendering when glArrayElement, glDrawArrays,
      glDrawElement, or glDrawRangeElements is called. See
      glTexCoordPointer.

  

  
If enabled, the vertex array is enabled for writing and used during
      rendering when glArrayElement, glDrawArrays,
      glDrawElement, or glDrawRangeElements is called. See
      glVertexPointer.










glEnableClientState is available only if the GL version is
    1.1 or greater.


If GL_ARB_multitexture is supported, enabling and disabling
    GL_TEXTURE_COORD_ARRAY affects the active client texture unit. The
    active client texture unit is controlled with
    glClientActiveTextureARB.








GL_INVALID_ENUM is generated if array is not an
    accepted value.


glEnableClientState is not allowed between the execution of
    glBegin and the corresponding glEnd, but an error may or may
    not be generated. If no error is generated, the behavior is undefined.
