NAME

cdmake - generate and fill a constant database

SYNTAX

#include "cdmake.h"

int cdb_make_start(struct cdb *c,int fd);
int cdb_make_add(struct cdb *c,char *key,unsigned int keylen,
char *data,unsigend int datalen);
int cdb_make_finish(struct cdb *c);

DESCRIPTION

cdb_make_start generates and intitialises a new cdb named c and makes it available via file descriptor fd.

cdb_make_add adds entries using the file descriptor fd given as key with length keylen into the cdb returning the hashed values data with length datalen.

cdb_make_finish finalises the data structure provided as fd.

RETURN CODES

Usually, the cdb_make_* routines provide a return code of 0 for successful operations and -1 if anything is going wrong.

EXAMPLE

#include <cdbmake.h>

  int fd;
  stralloc data = {0};
  stralloc key = {0};

struct cdb_make c;

  if (cdb_make_start(&c,fd) == -1) die_write();
  if (cdb_make_add(&c,key.s,key.len,data.s,data.len) == -1)
    die_write();
  if (cdb_make_finish(&c) == -1) die_write();
  if (fsync(fd) == -1) die_write();
