fdisk_set_script ()

int
fdisk_set_script (struct fdisk_context *cxt,
                  struct fdisk_script *dp);

Sets reference to the dp script and remove reference to the previously used script.

The script headers might be used by label drivers to overwrite built-in defaults (for example disk label Id) and label driver might optimize the default semantic to be more usable for scripts (for example to not ask for primary/logical/extended partition type).

Note that script also contains reference to the fdisk context (see fdisk_new_script()). This context may be completely independent on context used for fdisk_set_script().

fdisk_get_script ()

struct fdisk_script *
fdisk_get_script (struct fdisk_context *cxt);

fdisk_apply_script ()

int
fdisk_apply_script (struct fdisk_context *cxt,
                    struct fdisk_script *dp);

This function creates a new disklabel and partition within context cxt . You have to call fdisk_write_disklabel() to apply changes to the device.

fdisk_apply_script_headers ()

int
fdisk_apply_script_headers (struct fdisk_context *cxt,
                            struct fdisk_script *dp);

Associte context cxt with script dp and creates a new empty disklabel.

fdisk_new_script ()

struct fdisk_script *
fdisk_new_script (struct fdisk_context *cxt);

The script hold fdisk_table and additional information to read/write script to the file.

fdisk_new_script_from_file ()

struct fdisk_script *
fdisk_new_script_from_file (struct fdisk_context *cxt,
                            const char *filename);

Allocates a new script and reads script from filename .

fdisk_ref_script ()

void
fdisk_ref_script (struct fdisk_script *dp);

Incremparts reference counter.

fdisk_script_enable_json ()

int
fdisk_script_enable_json (struct fdisk_script *dp,
                          int json);

Disable/Enable JSON output format.

fdisk_script_get_header ()

const char *
fdisk_script_get_header (struct fdisk_script *dp,
                         const char *name);

fdisk_script_get_nlines ()

int
fdisk_script_get_nlines (struct fdisk_script *dp);

fdisk_script_get_table ()

struct fdisk_table *
fdisk_script_get_table (struct fdisk_script *dp);

The table (container with partitions) is possible to create by fdisk_script_read_context() or fdisk_script_read_file(), otherwise this function returns NULL.

fdisk_script_read_context ()

int
fdisk_script_read_context (struct fdisk_script *dp,
                           struct fdisk_context *cxt);

Reads data from the cxt context (on disk partition table) into the script. If the context is no specified than defaults to context used for fdisk_new_script().

Return: 0 on success, <0 on error.

fdisk_script_read_file ()

int
fdisk_script_read_file (struct fdisk_script *dp,
                        FILE *f);

Reads file f into script dp .

fdisk_script_read_line ()

int
fdisk_script_read_line (struct fdisk_script *dp,
                        FILE *f,
                        char *buf,
                        size_t bufsz);

Reads next line into dump.

fdisk_script_set_header ()

int
fdisk_script_set_header (struct fdisk_script *dp,
                         const char *name,
                         const char *data);

The headers are used as global options for whole partition table, always one header per line.

If no data is specified then the header is removed. If header does not exist and data is specified then a new header is added.

Note that libfdisk allows to specify arbitrary custom header, the default build-in headers are "unit" and "label", and some label specific headers (for example "uuid" and "name" for GPT).

fdisk_script_set_fgets ()

int
fdisk_script_set_fgets (struct fdisk_script *dp,
                        char* (*fn_fgets) (struct fdisk_script *, char *, size_t, FILE *));

The library uses fgets() function to read the next line from the script. This default maybe overrided to another function. Note that the function has to return the line terminated by \n (for example readline(3) removes \n).

Return: 0 on success, <0 on error

fdisk_script_write_file ()

int
fdisk_script_write_file (struct fdisk_script *dp,
                         FILE *f);

Writes script dp to the ile f .

fdisk_script_set_userdata ()

int
fdisk_script_set_userdata (struct fdisk_script *dp,
                           void *data);

Sets data usable for example in callbacks (e.g fdisk_script_set_fgets()).

fdisk_script_get_userdata ()

void *
fdisk_script_get_userdata (struct fdisk_script *dp);

fdisk_unref_script ()

void
fdisk_unref_script (struct fdisk_script *dp);

De-incremparts reference counter, on zero the dp is automatically deallocated.

struct fdisk_script

struct fdisk_script;

library handler for sfdisk compatible scripts and dumps
