Returns the number of errors on the error stack. If errors occur during this function call, the function returns (AT_ERRCOUNT)-1, but these errors are not appended onto the error stack. A value of zero means no ImageGear errors have occurred during your last IG_ function call.
This function does not process image pixels.
A call to this function has the same effect as a call to IG_err_error_check with nLevel equal to 0.
