glEnableClientState

NAME

glEnableClientState, glDisableClientState - enable or disable client-side capability

C SPECIFICATION

void glEnableClientState(GLenum cap)

PARAMETERS

cap

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)

PARAMETERS

cap

Specifies the capability to disable.

DESCRIPTION

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, cap, 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 glDrawArrays or glDrawElements is called. See glColorPointer.
GL_EDGE_FLAG_ARRAY: If enabled, the edge flag array is enabled for writing and used during rendering when glDrawArrays or glDrawElements is called. See glEdgeFlagPointer.
GL_INDEX_ARRAY: If enabled, the index array is enabled for writing and used during rendering when glDrawArrays or glDrawElements is called. See glIndexPointer.
GL_NORMAL_ARRAY: If enabled, the normal array is enabled for writing and used during rendering when glDrawArrays or glDrawElements is called. See glNormalPointer.
GL_TEXTURE_COORD_ARRAY: If enabled, the texture coordinate array is enabled for writing and used for rendering when glDrawArrays or glDrawElements is called. See glTexCoordPointer.
GL_VERTEX_ARRAY: If enabled, the vertex array is enabled for writing and used during rendering when glDrawArrays or glDrawElements is called. See glVertexPointer.

NOTES

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

ERRORS

GL_INVALID_ENUM is generated if cap 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.
