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

NAME

       glGetString - return a string describing the current GL connection

C SPECIFICATION

       const GLubyte* glGetString(GLenum name);

C SPECIFICATION

       const GLubyte* glGetStringi(GLenum name, GLuint index);

PARAMETERS

       name
	   Specifies a symbolic constant, one of GL_VENDOR, GL_RENDERER, GL_VERSION, or GL_SHADING_LANGUAGE_VERSION. Additionally, glGetStringi
	   accepts the GL_EXTENSIONS token.

       index
	   For glGetStringi, specifies the index of the string to return.

DESCRIPTION

       glGetString returns a pointer to a static string describing some aspect of the current GL connection.  name can be one of the following:

       GL_VENDOR

	   Returns the company responsible for this GL implementation. This name does not change from release to release.

       GL_RENDERER

	   Returns the name of the renderer. This name is typically specific to a particular configuration of a hardware platform. It does not
	   change from release to release.

       GL_VERSION

	   Returns a version or release number.

       GL_SHADING_LANGUAGE_VERSION

	   Returns a version or release number for the shading language.

       glGetStringi returns a pointer to a static string indexed by index.  name can be one of the following:

       GL_EXTENSIONS

	   For glGetStringi only, returns the extension string supported by the implementation at index.

       Strings GL_VENDOR and GL_RENDERER together uniquely specify a platform. They do not change from release to release and should be used by
       platform-recognition algorithms.

       The GL_VERSION and GL_SHADING_LANGUAGE_VERSION strings begin with a version number. The version number uses one of these forms:

       major_number.minor_number major_number.minor_number.release_number

       Vendor-specific information may follow the version number. Its format depends on the implementation, but a space always separates the
       version number and the vendor-specific information.

       All strings are null-terminated.

NOTES

       If an error is generated, glGetString returns 0.

       The client and server may support different versions.  glGetString always returns a compatible version number. The release number always
       describes the server.

ERRORS

       GL_INVALID_ENUM is generated if name is not an accepted value.

       GL_INVALID_VALUE is generated by glGetStringi if index is outside the valid range for indexed state name.

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.
