## Description

A GtkSourceMark marks a position in the text where you want to display additional info. It is based on GtkTextMark and thus is still valid after the text has changed though its position may change.

GtkSourceMarks are organised in categories which you have to set when you create the mark. Each category can have a priority, a pixbuf and other associated attributes. See `gtk_source_view_set_mark_attributes()`. The pixbuf will be displayed in the margin at the line where the mark residents if the “show-line-marks” property is set to `TRUE`. If there are multiple marks in the same line, the pixbufs will be drawn on top of each other. The mark with the highest priority will be drawn on top.

## Functions

### gtk_source_mark_new ()

    GtkSourceMark *
    gtk_source_mark_new (const gchar *name,
                         const gchar *category);

Creates a text mark. Add it to a buffer using `gtk_text_buffer_add_mark()`. If name is NULL, the mark is anonymous; otherwise, the mark can be retrieved by name using `gtk_text_buffer_get_mark()`. Normally marks are created using the utility function `gtk_source_buffer_create_source_mark()`.

#### Parameters

name | Name of the GtkSourceMark, can be NULL when not using a name |
category | is used to classify marks according to common characteristics (e.g. all the marks representing a bookmark could belong to the "bookmark" category, or all the marks representing a compilation error could belong to "error" category). |

#### Returns

a new GtkSourceMark that can be added using `gtk_text_buffer_add_mark()`.

Since: 2.2

### gtk_source_mark_get_category ()

    const gchar *
    gtk_source_mark_get_category (GtkSourceMark *mark);

Returns the mark category.

#### Parameters

mark | a GtkSourceMark. |

#### Returns

the category of the GtkSourceMark.

### gtk_source_mark_next ()

    GtkSourceMark *
    gtk_source_mark_next (GtkSourceMark *mark,
                          const gchar *category);

Returns the next GtkSourceMark in the buffer or `NULL` if the mark was not added to a buffer. If there is no next mark, `NULL` will be returned.

If `category` is `NULL`, looks for marks of any category.

#### Parameters

Returns the previous GtkSourceMark in the buffer or `NULL` if the mark was not added to a buffer. If there is no previous mark, `NULL` is returned.

If `category` is `NULL`, looks for marks of any category
