Synopsis
void raptor_free_memory (void *ptr); void* raptor_alloc_memory (size_t size); void* raptor_calloc_memory (size_t nmemb, size_t size);
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.
Details
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

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_parser_generate_id() handler
code to create new strings that will be used internally
as short identifiers and freed later on by the parsers.

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_parser_generate_id() handler
code to create new strings that will be used internally
as short identifiers and freed later on by the parsers.
