Some AmanithSVG functions may encounter errors. Unless otherwise specified, any value returned from a function following an error is undefined. An error condition within an AmanithSVG function must never result in process termination, with the exception of illegal memory accesses taking place within functions that accept an application provided pointer.

All AmanithSVG functions may signal SVGT_OUT_OF_MEMORY_ERROR. Such an error may occur midway through the execution of an AmanithSVG function, in which case the function may have caused changes to the state of AmanithSVG (or to drawing structures) prior to failure. When an AmanithSVG function encounters an error other than a SVGT_OUT_OF_MEMORY_ERROR, the context state is not modified and no drawing takes place.

All possible error codes are defined by the enumeration type SVGTErrorCode.

Error codeNotes
SVGT_NO_ERRORDefined as 0
SVGT_NOT_INITIALIZED_ERRORIt indicates that the library has not previously been initialized through the svgtInit function
SVGT_INVALID_SVG_ERRORReturned when the library detects that outermost element is not an <svg> element or there is a circular dependency (usually generated by <use> elements)
