Simple Database Library - a module to do data persistence in C, in size fixed rows, size fixed columns, no data types.

For small data, no index.

The key for register is the number of register.

Just compile with make command.

• SDBL_file_s *SDBL_open(const char *fname, int data_len)

Open file fname with register size of data_len characters, create if necessary. Returns a controller pointer.

• int SDBL_close(SDBL_file_s *fh)

Free internal structures and close controller fh.

• int SDBL_put(SDBL_file_s *finfo, SDBL_key_t key, char *data)

Save the register poitend by data into controller fh. If key is equal SDBL_NEW_RECORD, add a register, otherwise save a existent register pointed by key. Returns a true value if success.

• char *SDBL_get(SDBL_file_s *file, SDBL_key_t key)

Returns a register pointed by key.

• int SDBL_next(SDBL_file_s *)

Go to next register in file.

• int SDBL_prev(SDBL_file_s *)

Go to prev register in file.

• int SDBL_top(SDBL_file_s *)

Go to first register (top of file).

• int SDBL_bottom(SDBL_file_s *)

Go to last register in file (bottom of file).

See the test.c (type make test to compile).
