C extension API

[JDwangmo]

hello,where can i get the APIs of pytorch C extension function,such as THFloatTensor_resizeAs, THFloatTensor_add. Except those,has any function else? Thx.

#include <TH/TH.h>

Thanks you , but where can I find that file? @taineleau

When I compile in c++, the error： THFloatTensor_cadd is undefined
`#include <TH/TH.h>

int my_lib_add_forward(THFloatTensor *input1, THFloatTensor *input2,
THFloatTensor *output)
{
if (!THFloatTensor_isSameSizeAs(input1, input2))
return 0;
THFloatTensor_resizeAs(output, input1);
THFloatTensor_cadd(output, input1, 1.0, input2);
return 1;
}

int my_lib_add_backward(THFloatTensor *grad_output, THFloatTensor *grad_input)
{
THFloatTensor_resizeAs(grad_input, grad_output);
THFloatTensor_fill(grad_input, 1);
return 1;
}`
i use pytorch0.4.1

@lxtGH ,HI
When I compile in c++, print the error： THFloatTensor_cadd is undefined.
could give me some adavice.
