[Numpy-discussion] arrays : c aligmen to fortran and back

Thomas Hrabe thrabe@burnham....

PS: is there any public C library available which would perform the same operation?

like 
void* swap(int numberDimensions,int sizeDimensions,int dataSize,int conversionType,void* data); 
where conversionType is the flag fortran to c or vice versa.

As it works for numpy, there should be some public C/C++ code available... ???
I would like to have this python call in my C code (without calling an embedded function or so).
xf = np.asfortranarray(x)

Thank you very much,
Thomas

Yeah, this function does the job.
Thank you very much!

Does

xf = np.asfortranarray(x)

do what you want?
