NAME

ort_lang_sql — generate SQL schema of openradtool configuration

LIBRARY

library “libort-lang-sql”

SYNOPSIS

#include <sys/queue.h>
#include <stdio.h>
#include <ort.h>
#include <ort-lang-sql.h>

int
ort_lang_sql(const struct sql *args, const struct config *cfg, FILE *f);

DESCRIPTION

Outputs the SQL schema of the parsed configuration cfg to f. The output is tailored to sqlite3(1). The args is currently ignored and may be NULL.

RETURN VALUES

Returns zero on failure, non-zero on success. Failure only occurs with memory allocation errors or when writing to f.

EXAMPLES

The following emits a configuration as read from standard input to SQL as written to standard output.

struct config *cfg;
struct ort_lang_sql args;

memset(&args, 0, sizeof(struct ort_lang_sql));

if ((cfg = ort_config_alloc()) == NULL)
  err(1, NULL);
if (!ort_parse_file(cfg, stdin, "<stdin>"))
  errx(1, "ort_parse_file");
if (!ort_parse_close(cfg))
  errx(1, "ort_parse_close");
if (!ort_lang_sql(&args, cfg, stdout))
  err(1, "ort_lang_sql");

ort_config_free(cfg);

Alternatively, this could be converted into a string:

char *buf = NULL;
size_t bufsz = 0;

/* Read and parse configuration as above... */

if ((stream = open_memstream(&buf, &bufsz)) == NULL)
  err(1, "open_memstream");
if (!ort_lang_sql(&args, cfg, stream))
  err(1, "ort_lang_sql");
fclose(stream);

/* Do something with buf of size bufsz. */

free(buf);
