"""
This script generates a file called _identifiers that contains all Mbed TLS
identifiers found on internal headers. This is the equivalent of what was
previously `list-identifiers.sh --internal`, and is useful for generating an
exclusion file list for ABI/API checking, since we do not promise compatibility
for them.
It uses the NameCeck class from check_names.py to perform the parsing.
Returns 0 on success, 1 if there is a script error.
Must be run from Mbed TLS root.
