Memory

Memory — Memory handling functions

Functions

Description

Wrappers around the free, malloc and calloc functions but called from inside the library. Required by some systems to handle multiple-HEAPs and pass memory to and from the library.

Functions

raptor_free_memory ()

void
raptor_free_memory (void *ptr);

Free memory allocated inside raptor.

Some systems require memory allocated in a library to be deallocated in that library. This function allows memory allocated by raptor to be freed.

Examples include the result of the '_to_' methods that returns allocated memory such as raptor_uri_filename_to_uri_string, raptor_uri_filename_to_uri_string and raptor_uri_uri_string_to_filename_fragment

Parameters

ptr

memory pointer

 

raptor_alloc_memory ()

void *
raptor_alloc_memory (size_t size);

Allocate memory inside raptor.

Some systems require memory allocated in a library to be deallocated in that library. This function allows memory to be allocated inside the raptor shared library that can be freed inside raptor either internally or via raptor_free_memory.

Examples include using this in the raptor_world_generate_bnodeid() handler code to create new strings that will be used internally as short identifiers and freed later on by the parsers.

Parameters

size

size of memory to allocate

 

Returns

the address of the allocated memory or NULL on failure


raptor_calloc_memory ()

void *
raptor_calloc_memory (size_t nmemb,
                      size_t size);

Allocate zeroed array of items inside raptor.

Some systems require memory allocated in a library to be deallocated in that library. This function allows memory to be allocated inside the raptor shared library that can be freed inside raptor either internally or via raptor_free_memory.

Examples include using this in the raptor_world_generate_bnodeid() handler code to create new strings that will be used internally as short identifiers and freed later on by the parsers.

Parameters

nmemb

number of members

 

size

size of item

 

Returns

the address of the allocated memory or NULL on failure
