DESCRIPTION
The mdex_add function builds a merkle tree from data with length len and adds entries for both the tree and chunks to mdex .
The mdex_addfile function builds a merkle tree from the file or directory at path and adds entries for the trees and chunks to mdex .
The mdex_alias function adds an entry alias of length aliaslen which points to the entry hash of length hashlen which must already exist in mdex .
If q is not NULL, it must point to a queue q_t structure previously initialized with q_init (3). This will be passed through to mtree_build (3) to build the merkle tree. This is normally used in conjunction with a threadpool created with q_pool_create (3) with threads all calling q_job_seek (3).
The
flags
argument is the bitwise OR of zero of more of the following
flags:
MDEX_ALIAS
Entry is a pointer to another entry.
MDEX_RAND Entry should be sent using random symbols.
MDEX_RECURSE Recursively index all files and directories below path . (mdex_addfile)
MDEX_MOUNT
If set, stay within the same filesystem (i.e., do not cross
mount points).
MDEX_SYMLINK
Follow symbolic links when recursively indexing.
RETURN VALUE
These function return zero on success. On error, -1 is returned, and errno is set to indicate the error.
ERRORS
|
EINVAL |
Invalid argument. Both mdex and hash are required (not NULL), and hashlen > 0. |
ENOMEM Not enough space/cannot allocate memory (POSIX.1-2001).
