Pythondistutils.sysconfig模块中get_config_h_filename()函数的参数和返回值说明

The get_config_h_filename() function in the sysconfig module of distutils package is used to get the name of the C header file that contains configuration information for the current Python interpreter. This function takes no parameters and returns a string representing the name of the configuration header file.

Here is an explanation of the parameters and return value of the function along with an example of its usage:

Parameters:

- This function does not take any parameters.

Return Value:

- The function returns a string representing the name of the configuration header file.

Example:

import sysconfig

# Get the name of the configuration header file
config_h_filename = sysconfig.get_config_h_filename()
print("Configuration header file:", config_h_filename)

Output:

Configuration header file: /usr/include/python3.9/pyconfig.h

In the above example, we import the sysconfig module and then call the get_config_h_filename() function to retrieve the name of the configuration header file. We store the returned value in the config_h_filename variable and then print it. The output shows the full path of the configuration header file for the Python interpreter in use, which in this case is /usr/include/python3.9/pyconfig.h.

This function is useful when you need to access the configuration information provided by the Python interpreter at the C level. The configuration header file contains various macros and settings that are used during the compilation and linking of C extension modules.
