GStringChunk provides efficient storage of groups of strings

String chunks are used to store groups of strings. Memory is allocated in blocks, and as strings are added to the GStringChunk they are copied into the next free position in a block. When a block is full a new block is allocated.

When storing a large number of strings, string chunks are more efficient than using g_strdup() since fewer calls to malloc() are needed, and less memory is wasted in memory allocation overheads.

By adding strings with g_string_chunk_insert_const() it is also possible to remove duplicates.

To create a new GStringChunk use g_string_chunk_new().

To add strings to a GStringChunk use g_string_chunk_insert().

To add strings to a GStringChunk, but without duplicating strings which are already in the GStringChunk, use g_string_chunk_insert_const().

To free the entire GStringChunk use g_string_chunk_free(). It is not possible to free individual strings.



Creates a new GStringChunk.

Instance methods


Frees all strings contained within the GStringChunk. After calling g_string_chunk_clear() it is not safe to access any of the strings which were contained within it.

Frees all memory allocated by the GStringChunk. After calling g_string_chunk_free() it is not safe to access any of the strings which were contained within it.


Adds a copy of string to the GStringChunk. It returns a pointer to the new copy of the string in the GStringChunk. The characters in the string can be changed, if necessary, though you should not change anything after the end of the string.


Adds a copy of string to the GStringChunk, unless the same string has already been added to the GStringChunk with g_string_chunk_insert_const().


Adds a copy of the first len bytes of string to the GStringChunk. The copy is nul-terminated.
