Cython错误：将Integer数组传递给函数时，无法将Python对象转换为类型'int *'错误

Question

I am trying to pass an integer array to a function in Cython and I cannot understand why I get the error mentioned in the title.

A sample code of what I am trying to do is the following:

cpdef foo(int *table):
for i in range(10):
    table[i] = i

cdef int *temp=<int *>malloc(10*sizeof(int))
foo(temp)

for i in range(10):
    print temp[i]

I would appreciate any pointers as to how to pass the array correctly to the function. Thank you.

Answer 1

The issue here is the function is cpdef - this means it can be called from both C and Python code, and means all arguments must be Python objects (otherwise how would one call it from Python?)

Declare it as cdef instead.
