C SPECIFICATION    [Toc]    [Back]

     GLfloat* glcGetStringMetric( GLCenum inMetric,
				  GLfloat *outVec )

PARAMETERS    [Toc]    [Back]

     inMetric  Specifies the string to be measured.

     outVec    Specifies a vector in which the metric is stored.

DESCRIPTION    [Toc]    [Back]

     glcGetStringMetric	retrieves a string from	the GLC	measurement buffer,
     measures it, and stores the result	in outVec.

     To	store a	string in the measurement buffer, call glcMeasureCountedString
     or	glcMeasureString.

     If	glcGetStringMetric does	not raise an error, its	return value is
     outVec.

ERRORS    [Toc]    [Back]

     GLC_PARAMETER_ERROR is generated if inMetric is less than zero or is
     greater than or equal to the value	of the variable
     GLC_MEASURED_CHAR_COUNT.

     GLC_STATE_ERROR is	generated if the issuing thread	has no current GLC
     context.
