--- Comment #2 from Mark Wielaard <mark at klomp dot org> ---
A suggested C api was discussed here:
https://sourceware.org/pipermail/elfutils-devel/2021q4/004239.html
(see also the whole thread in the previous quarter)
/* Get info about an debuginfod artifact. Used to know whether
the target is already in local cache or whether it can be retrieved
from one if the urls contained in $DEBUGINFOD_URLS.
If build_id_len == 0, the build_id is supplied as a lowercase
hexadecimal string; otherwise it is a binary blob of given length.
If the requested resource is in cache, return a file descriptor
which an be used as is. If the requested resource can be found
through one of the DEBUGINFOD_URLS then -1 is returned and
file_size and transfer_size are set to the number of bytes of
the target file and the number if bytes that need to be transferred
from the server (file_size is the uncompressed size, transfer_size
might be the compressed size). Otherwise return -2 to indicate the
requested artifact cannot be found.
If the file wasn't in cache, but can be retrieved from a remote
server, then debuginfod_get_url () will return where the target
can be found. A successive debuginfod_find_* call will retieve
the resource (unless a network error occurs). */
int debuginfod_info_debuginfo (debuginfod_client *client,
const unsigned char *build_id,
int build_id_len,
size_t *size, size_t *transfer_size);
