Initialize the library.
int aug_insert(augeas *aug,
const char *path,
const char *label,
int before)
Create a new sibling LABEL for PATH by inserting into the tree just before PATH if BEFORE == 1 or just after PATH if BEFORE == 0.
int aug_label(const augeas *aug,
const char *path,
const char **label)
Lookup the label associated with PATH.
int aug_load(augeas *aug)
Load files into the tree.
int aug_match(const augeas *aug,

char ***matches)
the number of matches of the path expression PATH in AUG.
int aug_mv(augeas *aug,

Set the value associated with PATH to VALUE.
int aug_setm(augeas *aug,
const char *base,
const char *sub,
const char *value)
Set the value of multiple nodes in one operation.
int aug_span(augeas *aug,

int aug_text_retrieve(struct augeas *aug,
const char *lens,
const char *node_in,
const char *path,
const char *node_out)
Transform the tree at PATH into a string using lens LENS and store it in the node NODE_OUT, assuming the tree was initially generated using the value of node NODE_IN.
int aug_text_store(augeas *aug,
const char *lens,
const char *node,
const char *path)
Use the value of node NODE as a string and transform it into a tree using the lens LENS and store it in the tree at PATH, which will be overwritten.

struct augeas
The data structure representing a connection to Augeas.
Control what save does when renaming the temporary file to its final destination fails with EXDEV or EBUSY: when this tree node exists, copy the file contents.
Context prepended to all non-absolute paths
The root for actual file contents
The default location for lens definitions
Information about files
The root directory
How we save files.
Information about text (see aug_text_store and aug_text_retrieve)
Augeas reports some information in this subtree
The env var that points to the chroot holding files we may modify.
Enable or disable node indexes
int __aug_close_memstream(struct memstream *ms)
