.SH NAME
cdmake \- generate and fill a constant database
.SH SYNTAX
.B #include \(dqcdmake.h\(dq
int \fBcdb_make_start\fP(struct cdb *\fIc\fR,int \fIfd\fR);
.br
int \fBcdb_make_add\fP(struct cdb *\fIc\fR,char *\fIkey\fR,unsigned int \fIkeylen\fR,
char *\fIdata\fR,unsigend int \fIdatalen\fR);
.br
int \fBcdb_make_finish\fP(struct cdb *\fIc\fR);
.SH DESCRIPTION
.B cdb_make_start
generates and intitialises a new cdb named
.I c
and makes it available via file descriptor
.IR fd .
.B cdb_make_add
adds entries using the file descriptor
.I fd
given as
.I key
with length
.I keylen
into the cdb returning the hashed values
.I data
with length
.IR datalen .
.B cdb_make_finish
finalises the data structure provided as
.IR fd .
.SH "RETURN CODES"
Usually, the
.B cdb_make_*
routines provide a return code of
.I 0
for successful operations and
.I -1
if anything is going wrong.
.SH 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();
