+/**
+ * \file resource-index.c
+ *
+ * Tests GetProgramResourceIndex interface.
+ *
+ * From the GL_ARB_program_interface_query spec:
+ *     "The command returns the unsigned integer index assigned to a
+ *     resource named <name> in the interface type <programInterface> of
+ *     program object <program>.  The error INVALID_ENUM is generated if
+ *     <programInterface> is ATOMIC_COUNTER_BUFFER, since active atomic
+ *     counter buffer resources are not assigned name strings.
+ *
+ *     If <name> exactly matches the name string of one of the active
+ *     resources for <programInterface>, the index of the matched
+ *     resource is returned. Additionally, if <name> would exactly match
+ *     the name string of an active resource if "[0]" were appended to <name>,
+ *     the index of the matched resource is returned.  Otherwise, <name> is
+ *     considered not to be the name of an active resource, and INVALID_INDEX
+ *     is returned.  Note that if an interface enumerates a single active
+ *     resource list entry for an array variable (e.g., "a[0]"), a <name>
+ *     identifying any array element other than the first (e.g., "a[1]")
+ *     is not considered to match.
+ *
+ *     For the interface TRANSFORM_FEEDBACK_VARYING, the value INVALID_INDEX
+ *     should be returned when querying the index assigned to the special
+ *     names "gl_NextBuffer", "gl_SkipComponents1", "gl_SkipComponents2",
+ *     "gl_SkipComponents3", and "gl_SkipComponents4".
