fs.h
Filesystem walk and stat functions.

indexread
int indexread(struct index_s *idx, FILE *s)
Reads a file stream and deserializes the contents into a map of individual file nodes.
Definition index.c:80

indexlist
struct inode_s ** indexlist(const struct index_s *idx)
Flattens the index map into an unsorted array of nodes. The list is dynamically allocated and must be...
Definition index.c:136

indexwrite
int indexwrite(struct index_s *idx, FILE *s)
Flattens the index map into a sorted array of nodes (by filepath). The list is then written to the fi...
Definition index.c:59

INDEXBUCKETS
#define INDEXBUCKETS
The fixed number of buckets in the index map.
Definition index.h:22

indexput
struct inode_s * indexput(struct index_s *idx, struct inode_s node)
Copies the node and inserts it into the index mapping. The copy is by assignment, so pointers within ...
Definition index.c:111

indexfind
struct inode_s * indexfind(const struct index_s *idx, const char *fp)
Searches the index for a node with a matching filepath.
