    I would like to find out if there is an Xlib command
    similar to the GKS command gpolymarker.

No, there isn't.  You can either use multiple points per marker, or
explicitly draw an X or a hollow circle, or you a text symbol.

    I have thought of just placing the text symbol for the 'o' to the
    screen, but text characters are not centered about an x,y location,
    they are merely placed to the right of the specified starting
    location.

Glyphs aren't centered on the x,y position you specify, but you can
certainly find out the ink width and height of the glyph, and the
baseline, and compute a relative x,y position to achieve centering.
