GLPATCHPARAMETER(3G)						  [FIXME: manual]					      GLPATCHPARAMETER(3G)

NAME

       glPatchParameter - specifies the parameters for patch primitives

C SPECIFICATION

       void glPatchParameteri(GLenum pname, GLint value);

       void glPatchParameterfv(GLenum pname, const GLfloat *values);

PARAMETERS

       pname
	   Specifies the name of the parameter to set. The symbolc constants GL_PATCH_VERTICES, GL_PATCH_DEFAULT_OUTER_LEVEL, and
	   GL_PATCH_DEFAULT_INNER_LEVEL are accepted.

       value
	   Specifies the new value for the parameter given by pname.

       values
	   Specifies the address of an array containing the new values for the parameter given by pname.

DESCRIPTION

       glPatchParameter specifies the parameters that will be used for patch primitives.  pname specifies the parameter to modify and must be
       either GL_PATCH_VERTICES, GL_PATCH_DEFAULT_OUTER_LEVEL or GL_PATCH_DEFAULT_INNER_LEVEL. For glPatchParameteri, value specifies the new
       value for the parameter specified by pname. For glPatchParameterfv, values specifies the address of an array containing the new values for
       the parameter specified by pname.

       When pname is GL_PATCH_VERTICES, value specifies the number of vertices that will be used to make up a single patch primitive. Patch
       primitives are consumed by the tessellation control shader (if present) and subsequently used for tessellation. When primitives are
       specified using glDrawArrays() or a similar function, each patch will be made from parameter control points, each represented by a vertex
       taken from the enabeld vertex arrays.  parameter must be greater than zero, and less than or equal to the value of GL_MAX_PATCH_VERTICES.

       When pname is GL_PATCH_DEFAULT_OUTER_LEVEL or GL_PATCH_DEFAULT_INNER_LEVEL, values contains the address of an array contiaining the default
       outer or inner tessellation levels, respectively, to be used when no tessellation control shader is present.

ERRORS

       GL_INVALID_ENUM is generated if pname is not an accepted value.

       GL_INVALID_VALUE is generated if pname is GL_PATCH_VERTICES and value is less than or equal to zero, or greater than the value of
       GL_MAX_PATCH_VERTICES.

GLGETQUERYINDEXEDIV(3G) 					  [FIXME: manual]					   GLGETQUERYINDEXEDIV(3G)

NAME

       glGetQueryIndexediv - return parameters of an indexed query object target

C SPECIFICATION

       void glGetQueryIndexediv(GLenum target, GLuint index, GLenum pname, GLint * params);

PARAMETERS

       target
	   Specifies a query object target. Must be GL_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED, GL_PRIMITIVES_GENERATED,
	   GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN, GL_TIME_ELAPSED, or GL_TIMESTAMP.

       index
	   Specifies the index of the query object target.

       pname
	   Specifies the symbolic name of a query object target parameter. Accepted values are GL_CURRENT_QUERY or GL_QUERY_COUNTER_BITS.

       params
	   Returns the requested data.

DESCRIPTION

       glGetQueryIndexediv returns in params a selected parameter of the indexed query object target specified by target and index.  index
       specifies the index of the query object target and must be between zero and a target-specific maxiumum.

       pname names a specific query object target parameter. When pname is GL_CURRENT_QUERY, the name of the currently active query for the
       specified index of target, or zero if no query is active, will be placed in params. If pname is GL_QUERY_COUNTER_BITS, the
       implementation-dependent number of bits used to hold the result of queries for target is returned in params.

NOTES

       If an error is generated, no change is made to the contents of params.

       Calling glGetQueryiv() is equivalent to calling glGetQueryIndexediv with index set to zero.

ERRORS

       GL_INVALID_ENUM is generated if target or pname is not an accepted value.

       GL_INVALID_VALUE is generated if index is greater than or equal to the target-specific maximum.
