  27  * Tests the error cases of the GetProgramResourceName interface. The real
  28  * functional test is resource-query.
  29  *
  30  * From the GL_ARB_program_interface_query spec:
  31  *      "The command
  32  *
  33  *      void GetProgramResourceName(uint program, enum programInterface,
  34  *                                  uint index, sizei bufSize, sizei *length,
  35  *                                  char *name);
  36  *
  37  *      returns the name string assigned to the single active resource with an
  38  *      index of <index> in the interface <programInterface> of program object
  39  *      <program>.  The error INVALID_VALUE is generated if <index> is greater
  40  *      than or equal to the number of entries in the active resource list for
  41  *      <programInterface>.  The error INVALID_ENUM is generated if
  42  *      <programInterface> is ATOMIC_COUNTER_BUFFER, since active atomic counter
  43  *      buffer resources are not assigned name strings.
  44  *
  45  *      The name string assigned to the active resource identified by <index> is
  46  *      returned as a null-terminated string in <name>.  The actual number of
  47  *      characters written into <name>, excluding the null terminator, is
  48  *      returned in <length>.  If <length> is NULL, no length is returned. The
  49  *      maximum number of characters that may be written into <name>, including
  50  *      the null terminator, is specified by <bufSize>.  If the length of the
  51  *      name string (including the null terminator) is greater than <bufSize>,
  52  *      the first <bufSize>-1 characters of the name string will be written to
  53  *      <name>, followed by a null terminator.  If <bufSize> is zero, no error
  54  *      will be generated but no characters will be written to <name>.  The
  55  *      length of the longest name string for <programInterface>, including a
  56  *      null terminator, can be queried by calling GetProgramInterfaceiv with a
  57  *      <pname> of MAX_NAME_LENGTH.
  58  *
  59  *      [...]
  60  *
  61  *      An INVALID_VALUE error is generated by GetProgramInterfaceiv,
  62  *      GetProgramResourceIndex, GetProgramResourceName, GetProgramResourceiv,
  63  *      GetProgramResourceLocation, and GetProgramResourceLocationIndex if
  64  *      <program> is not the name of either a shader or program object.
  65  *
  66  *      An INVALID_OPERATION error is generated by GetProgramInterfaceiv,
  67  *      GetProgramResourceIndex, GetProgramResourceName, GetProgramResourceiv,
  68  *      GetProgramResourceLocation, and GetProgramResourceLocationIndex if
  69  *      <program> is the name of a shader object.
  70  *
  71  *      [...]
  72  *
  73  *      INVALID_VALUE is generated by GetProgramResourceName if <index> is
  74  *      greater than or equal to the number of entries in the active resource
  75  *      list for <programInterface>.
  76  *
  77  *      INVALID_ENUM is generated by GetProgramResourceName if
  78  *      <programInterface> is ATOMIC_COUNTER_BUFFER."
