Function Documentation

void GLAPIENTRY _mesa_GetBooleanv	(	GLenum	pname,
		GLboolean *	params
	)

void GLAPIENTRY _mesa_GetDoublev	(	GLenum	pname,
		GLdouble *	params
	)

GLenum GLAPIENTRY _mesa_GetError

(

void

)

Returns the current GL error code, or GL_NO_ERROR.

Returns:

current error code

Returns __GLcontextRec::ErrorValue.

void GLAPIENTRY _mesa_GetFloatv	(	GLenum	pname,
		GLfloat *	params
	)

void GLAPIENTRY _mesa_GetInteger64v	(	GLenum	pname,
		GLint64 *	params
	)

void GLAPIENTRY _mesa_GetIntegerv	(	GLenum	pname,
		GLint *	params
	)

void GLAPIENTRY _mesa_GetPointerv	(	GLenum	pname,
		GLvoid **	params
	)

Return pointer-valued state, such as a vertex array pointer.

Parameters:

	pname	names state to be queried
	params	returns the pointer value

See also:

glGetPointerv().

Tries to get the specified pointer via dd_function_table::GetPointerv, otherwise gets the specified pointer from the current context.

const GLubyte* GLAPIENTRY _mesa_GetString

(

GLenum

name

)

Query string-valued state.

The return value should _not_ be freed by the caller.

Parameters:

name

the state variable to query.

See also:

glGetString().

Tries to get the string from dd_function_table::GetString, otherwise returns the hardcoded strings.
