|
The subdir_glob() function is useful for defining header maps for C/C++

libraries which should be relative the given sub-directory.
|
|
Given a list of tuples, the form of (relative-sub-directory, glob-pattern),
|

it returns a dict of sub-directory relative paths to full paths.

|
|
|
Please refer to native.glob() for explanations and examples of the pattern.

Args:

glob_specs: The array of tuples in form of

|
|
type: List[Tuple[str, str]]

exclude: A list of patterns to identify files that should be removed

from the set specified by the first argument. Defaults to [].

type: Optional[List[str]]

prefix: If is not None, prepends it to each key in the dictionary.

Defaults to None.
