icetGetError(3) IceT Reference icetGetError(3) NAME
icetGetError -- return the last error condition. Synopsis #include <IceT.h> GLenum icetGetError( void ); Description Retrieves the first error or warning condition that occurred since the last call to icetGetError or since program startup, whichever hap- pened last. Once an error condition has been retrieved with icetGetError, the error condition is reset to no error and cannot be retrieved again. Return Value One of the following flags will be returned: ICET_INVALID_VALUE An inappropriate value has been passed to a function. ICET_INVALID_OPERATION An inappropriate function has been called. ICET_OUT_OF_MEMORY IceT has ran out of memory for buffer space. ICET_BAD_CAST A function has been passed a value of the wrong type. ICET_INVALID_ENUM A function has been passed an invalid constant. ICET_SANITY_CHECK_FAIL An internal error (or warning) has occurred. ICET_NO_ERROR No error has been raised since the last call to icetGetError. Bugs It is not possible to tell if the returned value was caused by an error or a warning. Notes The error value is not context dependent.

icetImageNull(3) IceT Reference icetImageNull(3) NAME
icetImageNull -- retrieve a placeholder for an empty image. Synopsis #include <IceT.h> IceTImage icetImageNull( void ); Description Images are created internally by the IceT library. Sometimes it is convenient to have a placeholder for a .igimage!null``null'' image, an image that does not and cannot hold data. Null images require no allocated memory to function. If your code has the potential of using an IceTImage image object that might not otherwise be initialized, use icetImageNull to set it to a null object. This will ensure that IceT image functions that operate on it will behave deterministically. A null image simply looks like an image with no pixels and has no color buffers. icetImageGetWidth, icetImageGetHeight, and icetImageGet- NumPixels all return 0 for a null image. icetSetColorFormatand icetSetDepthFormatreturn ICET_IMAGE_COLOR_NONE and ICET_IMAGE_DEPTH_NONE, respectively. You can identify a null image with the icetImageIsNull function. Return Value A null image object. Errors None. Warnings None. Bugs None known.
