GLPATCHPARAMETER(3G)						   OpenGL 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. SEE ALSO

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

NAME
glGetProgramPipeline - retrieve properties of a program pipeline object C SPECIFICATION
void glGetProgramPipelineiv(GLuint pipeline, GLenum pname, GLint *params); PARAMETERS
pipeline Specifies the name of a program pipeline object whose parameter retrieve. pname Specifies the name of the parameter to retrieve. params Specifies the address of a variable into which will be written the value or values of pname for pipeline. DESCRIPTION
glGetProgramPipelineiv retrieves the value of a property of the program pipeline object pipeline. pname specifies the name of the parameter whose value to retrieve. The value of the parameter is written to the variable whose address is given by params. If pname is GL_ACTIVE_PROGRAM, the name of the active program object of the program pipeline object is returned in params. If pname is GL_VERTEX_SHADER, the name of the current program object for the vertex shader type of the program pipeline object is returned in params. If pname is GL_TESS_CONTROL_SHADER, the name of the current program object for the tessellation control shader type of the program pipeline object is returned in params. If pname is GL_TESS_EVALUATION_SHADER, the name of the current program object for the tessellation evaluation shader type of the program pipeline object is returned in params. If pname is GL_GEOMETRY_SHADER, the name of the current program object for the geometry shader type of the program pipeline object is returned in params. If pname is GL_FRAGMENT_SHADER, the name of the current program object for the fragment shader type of the program pipeline object is returned in params. If pname is GL_INFO_LOG_LENGTH, the length of the info log, including the null terminator, is returned in params. If there is no info log, zero is returned. ERRORS
GL_INVALID_OPERATION is generated if pipeline is not zero or a name previously returned from a call to glGenProgramPipelines() or if such a name has been deleted by a call to glDeleteProgramPipelines(). GL_INVALID_ENUM is generated if pname is not one of the accepted values. SEE ALSO
