PARAMETERS
       flag  Specifies the current edge flag value, either GL_TRUE or GL_FALSE.
             The initial value is GL_TRUE.

C SPECIFICATION
       void GLAPIENTRY glEdgeFlagv( const GLboolean *flag )

PARAMETERS
       flag   Specifies a pointer to an array that contains  a  single  boolean
              element, which replaces the current edge flag value.

DESCRIPTION
       Each  vertex  of a polygon, separate triangle, or separate quadrilateral
       specified between a glBegin/glEnd pair is marked as the start of  either
       a  boundary  or nonboundary edge.  If the current edge flag is true when
       the vertex is specified, the vertex is marked as the start of a boundary
       edge.   Otherwise,  the  vertex  is marked as the start of a nonboundary
       edge.  glEdgeFlag sets the edge flag bit to GL_TRUE if flag is  GL_TRUE,
       and to GL_FALSE otherwise.

       The vertices of connected triangles and connected quadrilaterals are al‐
       ways marked as boundary, regardless of the value of the edge flag.

       Boundary and nonboundary edge flags on vertices are significant only  if
       GL_POLYGON_MODE is set to GL_POINT or GL_LINE.  See glPolygonMode.

NOTES
       The  current  edge  flag  can  be  updated  at any time.  In particular,
       glEdgeFlag can be called between a call to glBegin and the corresponding
       call to glEnd.
