bsalomon@google.com0b77d682011-08-19 13:28:54 +0000[diff] [blame]18 * Rather than depend on platform-specific GL headers and libraries, we require
19 * the client to provide a struct of GL function pointers. This struct can be
20 * specified per-GrContext as a parameter to GrContext::Create. If NULL is
commit-bot@chromium.orga3b15ed2014-01-15 19:32:03 +0000[diff] [blame]21 * passed to Create then a "default" GL interface is created. If the default is
bsalomon@google.com0b77d682011-08-19 13:28:54 +0000[diff] [blame]22 * also NULL GrContext creation will fail.
23 *
bsalomon@google.com6fb736f2011-09-16 18:51:57 +0000[diff] [blame]24 * The default interface is returned by GrGLDefaultInterface. This function's
robertphillips@google.com0da37192012-03-19 14:42:13 +0000[diff] [blame]25 * implementation is platform-specific. Several have been provided, along with
commit-bot@chromium.orga3b15ed2014-01-15 19:32:03 +0000[diff] [blame]26 * an implementation that simply returns NULL.

28 * By defining GR_GL_PER_GL_CALL_IFACE_CALLBACK to 1 the client can specify a
29 * callback function that will be called prior to each GL function call. See
