Strings

struct GString

struct GString
{
  gchar *str;
  gint len;
};

The GString struct contains the public fields of a GString. The str field points to the character data. It may move as text is added. The len field contains the length of the string, not including the terminating null character.

The str field is zero-terminated and so can be used as an ordinary C string. But it may be moved when text is appended or inserted into the string.

g_string_new ()

GString*    g_string_new                    (const gchar *init);

Creates a new GString, initialized with the given string.

g_string_sized_new ()

GString*    g_string_sized_new              (guint dfl_size);

Creates a new GString, with enough space for dfl_size characters. This is useful if you are going to add a lot of text to the string and don't want it to be reallocated too often.

g_string_assign ()

GString*    g_string_assign                 (GString *lval,
                                             const gchar *rval);

Copies the characters from one GString into another, destroying any previous contents. It is rather like the standard strcpy() function, except that you do not have to worry about having enough space to copy the string.

g_string_sprintf ()

void        g_string_sprintf                (GString *string,
                                             const gchar *format,
                                             ...);

Writes a formatted string into a GString. This is similar to the standard sprintf() function, except that the GString buffer automatically expands to contain the results. The previous contents of the GString are destroyed.

g_string_sprintfa ()

void        g_string_sprintfa               (GString *string,
                                             const gchar *format,
                                             ...);

Appends a formatted string onto the end of a GString. This function is is similar to g_string_sprintf() except that the text is appended to the GString.

g_string_append ()

GString*    g_string_append                 (GString *string,
                                             const gchar *val);

Adds a string onto the end of a GString, expanding it if necessary.

g_string_append_c ()

GString*    g_string_append_c               (GString *string,
                                             gchar c);

Adds a character onto the end of a GString, expanding it if necessary.

g_string_prepend ()

GString*    g_string_prepend                (GString *string,
                                             const gchar *val);

Adds a string on to the start of a GString, expanding it if necessary.

g_string_prepend_c ()

GString*    g_string_prepend_c              (GString *string,
                                             gchar c);

Adds a character onto the start of a GString, expanding it if necessary.

g_string_insert ()

GString*    g_string_insert                 (GString *string,
                                             gint pos,
                                             const gchar *val);

Inserts a copy of a string into a GString, expanding it if necessary.

g_string_insert_c ()

GString*    g_string_insert_c               (GString *string,
                                             gint pos,
                                             gchar c);

Inserts a character into a GString, expanding it if necessary.

g_string_erase ()

GString*    g_string_erase                  (GString *string,
                                             gint pos,
                                             gint len);

Removes len characters from a GString, starting at position pos. The rest of the GString is shifted down to fill the gap.

g_string_truncate ()

GString*    g_string_truncate               (GString *string,
                                             gint len);

Cuts off the end of the GString, leaving the first len characters.

g_string_free ()

void        g_string_free                   (GString *string,
                                             gint free_segment);

Frees the memory allocated for the GString. If free_segment is TRUE it also frees the character data.

g_string_up ()

GString*    g_string_up                     (GString *string);

Converts a GString to upper case.

g_string_down ()

GString*    g_string_down                   (GString *string);

Converts a GString to lower case.
