GLGETMULTISAMPLEFV(3G)				    OpenGL Manual			       GLGETMULTISAMPLEFV(3G)

NAME
glGetMultisamplefv - retrieve the location of a sample
C SPECIFICATION
void glGetMultisamplefv(GLenum pname, GLuint index, GLfloat *val);
PARAMETERS
pname Specifies the sample parameter name. pname must be GL_SAMPLE_POSITION. index Specifies the index of the sample whose position to query. val Specifies the address of an array to receive the position of the sample.
DESCRIPTION
glGetMultisamplefv queries the location of a given sample. pname specifies the sample parameter to retrieve and must be GL_SAMPLE_POSITION. index corresponds to the sample for which the location should be returned. The sample location is returned as two floating-point values in val[0] and val[1], each between 0 and 1, corresponding to the x and y locations respectively in the GL pixel space of that sample. (0.5, 0.5) this corresponds to the pixel center. index must be between zero and the value of GL_SAMPLES - 1. If the multisample mode does not have fixed sample locations, the returned values may only reflect the locations of samples within some pixels.
ERRORS
GL_INVALID_ENUM is generated if pname is not one GL_SAMPLE_POSITION. GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_SAMPLES.
