From 50aaabc248c9823106ff772873cbf2631d4dadcd Mon Sep 17 00:00:00 2001 From: George Sapountzis Date: Fri, 13 Apr 2007 18:12:37 +0300 Subject: xmesa: export xmesa functions used by xfree86. This uses xmesa.h as the GLcore interface and avoids adding an explicit GLcore inteface which would not be a proper interface anyway. It puts the declarations of the three functions specific for XMesa/XFree86 in xmesa.h, we can push them down to xmesa_xf86.h if hiding behind XFree86Server ifdef's is not enough. --- src/mesa/drivers/x11/xm_api.c | 19 +++++++++++++++---- src/mesa/drivers/x11/xmesaP.h | 10 ---------- 2 files changed, 15 insertions(+), 14 deletions(-) (limited to 'src/mesa/drivers/x11') diff --git a/src/mesa/drivers/x11/xm_api.c b/src/mesa/drivers/x11/xm_api.c index 24028a44ba..6439d13fa5 100644 --- a/src/mesa/drivers/x11/xm_api.c +++ b/src/mesa/drivers/x11/xm_api.c @@ -1308,6 +1308,7 @@ xmesa_convert_from_x_visual_type( int visualType ) * visualCaveat - ala the GLX extension, usually GLX_NONE * Return; a new XMesaVisual or 0 if error. */ +PUBLIC XMesaVisual XMesaCreateVisual( XMesaDisplay *display, XMesaVisualInfo visinfo, GLboolean rgb_flag, @@ -1450,6 +1451,7 @@ XMesaVisual XMesaCreateVisual( XMesaDisplay *display, } +PUBLIC void XMesaDestroyVisual( XMesaVisual v ) { #ifndef XFree86Server @@ -1467,6 +1469,7 @@ void XMesaDestroyVisual( XMesaVisual v ) * lists or NULL if no sharing is wanted. * \return an XMesaContext or NULL if error. */ +PUBLIC XMesaContext XMesaCreateContext( XMesaVisual v, XMesaContext share_list ) { static GLboolean firstTime = GL_TRUE; @@ -1550,6 +1553,7 @@ XMesaContext XMesaCreateContext( XMesaVisual v, XMesaContext share_list ) +PUBLIC void XMesaDestroyContext( XMesaContext c ) { GLcontext *mesaCtx = &c->mesa; @@ -1721,7 +1725,7 @@ XMesaCreateWindowBuffer2(XMesaVisual v, XMesaWindow w, XMesaContext c) } -XMesaBuffer +PUBLIC XMesaBuffer XMesaCreateWindowBuffer(XMesaVisual v, XMesaWindow w) { return XMesaCreateWindowBuffer2( v, w, NULL ); @@ -1737,7 +1741,7 @@ XMesaCreateWindowBuffer(XMesaVisual v, XMesaWindow w) * \c GLX_DIRECT_COLOR visual for the pixmap * \returns new XMesaBuffer or NULL if error */ -XMesaBuffer +PUBLIC XMesaBuffer XMesaCreatePixmapBuffer(XMesaVisual v, XMesaPixmap p, XMesaColormap cmap) { int client = 0; @@ -1802,7 +1806,7 @@ XMesaCreatePBuffer(XMesaVisual v, XMesaColormap cmap, /* * Deallocate an XMesaBuffer structure and all related info. */ -void +PUBLIC void XMesaDestroyBuffer(XMesaBuffer b) { xmesa_free_buffer(b); @@ -1845,6 +1849,7 @@ GLboolean XMesaMakeCurrent( XMesaContext c, XMesaBuffer b ) /* * Bind buffer b to context c and make c the current rendering context. */ +PUBLIC GLboolean XMesaMakeCurrent2( XMesaContext c, XMesaBuffer drawBuffer, XMesaBuffer readBuffer ) { @@ -1958,6 +1963,8 @@ XMesaBuffer XMesaGetCurrentReadBuffer( void ) } +#ifdef XFree86Server +PUBLIC GLboolean XMesaForceCurrent(XMesaContext c) { if (c) { @@ -1976,6 +1983,7 @@ GLboolean XMesaForceCurrent(XMesaContext c) } +PUBLIC GLboolean XMesaLoseCurrent(XMesaContext c) { (void) c; @@ -1984,11 +1992,13 @@ GLboolean XMesaLoseCurrent(XMesaContext c) } +PUBLIC GLboolean XMesaCopyContext( XMesaContext xm_src, XMesaContext xm_dst, GLuint mask ) { _mesa_copy_context(&xm_src->mesa, &xm_dst->mesa, mask); return GL_TRUE; } +#endif /* XFree86Server */ /* @@ -2135,6 +2145,7 @@ static void FXgetImage( XMesaBuffer b ) * Copy the back buffer to the front buffer.
