The functions for dealing with errors are in augeas.h; they are:
typedef enum {
AUG_NOERROR, /* No error */
AUG_ENOMEM, /* Out of memory */
AUG_EINTERNAL, /* Internal error (bug) */
AUG_EPATHX, /* Invalid path expression */
AUG_ENOMATCH, /* No match for path expression */
AUG_EMMATCH /* Too many matches for path expression */
} aug_errcode_t;
/* Return the error code from the last API call */
int aug_error(augeas *aug);
/* Return a human-readable message for the error code */
const char *aug_error_message(augeas *aug);
/* Return a human-readable message elaborating the error code; might be
* NULL. For example, when the error code is AUG_EPATHX, this will
explain
* how the path expression is invalid */
const char *aug_error_minor_message(augeas *aug);
/* Return details about the error, which might be NULL. For example, for
* AUG_EPATHX, indicates where in the path expression the error
* occurred. The returned value can only be used until the next API call
*/
const char *aug_error_details(augeas *aug);
