Function Documentation

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_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.

static const char* compute_version

(

const GLcontext *

ctx

)

[static]

Examine enabled GL extensions to determine GL version.

Returns:

version string
