GLENABLECLIENTSTATE(3UNIX Programmer's ManGLENABLECLIENTSTATE(3G)
NAME
glEnableClientState, glDisableClientState - enable or dis-
able client-side capability
C SPECIFICATION
void glEnableClientState( GLenum cap); 1.1 )
PARAMETERS
1.1 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 cap); 1.1 )
PARAMETERS
1.1 Specifies the capability to disable.
DESCRIPTION
glEnableClientState and glDisableClientState enable or dis-
able individual client-side capabilities. By default, all
client-side capabilities are disabled. Both
glEnableClientState and glDisableClientState take a single
argument, 1.1, which can assume one of the following values:
GL_COLOR_ARRAY If enabled, the color array is
enabled for writing and used during
rendering when glArrayElement,
glDrawArrays, glDrawElement, or
glDrawRangeElements is called. See
glColorPointer.
GL_EDGE_FLAG_ARRAY If enabled, the edge flag array is
enabled for writing and used during
rendering when glArrayElement,
glDrawArrays, glDrawElement, or
glDrawRangeElements is called. See
glEdgeFlagPointer.
GL_INDEX_ARRAY If enabled, the index array is
enabled for writing and used during
rendering when glArrayElement,
glDrawArrays, glDrawElement, or
glDrawRangeElements is called. See
glIndexPointer.
GL_NORMAL_ARRAY If enabled, the normal array is
enabled for writing and used during

rendering when glArrayElement,
glDrawArrays, glDrawElement, or
glDrawRangeElements is called. See
glNormalPointer.
GL_TEXTURE_COORD_ARRAY If enabled, the texture coordinate
array is enabled for writing and
used during rendering when
glArrayElement, glDrawArrays,
glDrawElement, or
glDrawRangeElements is called. See
glTexCoordPointer.
GL_VERTEX_ARRAY If enabled, the vertex array is
enabled for writing and used during
rendering when glArrayElement,
glDrawArrays, glDrawElement, or
glDrawRangeElements is called. See
glVertexPointer.
NOTES
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.
ERRORS
GL_INVALID_ENUM is generated if 1.1 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.
