Walk error stack




H5E.walk(direction,func) walks the error stack for the current thread and calls the specified function for each error along the way. func is a function handle. direction specifies how the error stack is traversed and can be given by one of the following strings or the numeric equivalent.


The specified function must have the following signature:

status = func(n,error_struct)

where n is the indexed position of the error in the stack and error_struct is a structure with the following fields:

maj_numMajor error number
min_numMinor error number
func_nameFunction in which the error occurred
file_nameFile in which the error occurred
lineLine in file where error occurs
