What is the corresponding C-api name of the following numpy function in Python

Question

• I wanna write a C extension lib for Python, aiming to replace Python code with C.
• and the Python codes has several lines like below:

import numpy as np
a = np.array([1,3,12,0.43,234,-3,-4])
b = a[[1,3,5]]
print(b)

# array([ 3.  ,  0.43, -3.  ])

• Different from an int as the index of a numpy array, this example treats an array as an index.

• I am confused that getting the designated indexes of a given numpy array, what is the corresponding C-API name?

• the NUMPY C-API files is in numpy c-api

• Thanks very much.
