NAME

       hashkit_is_allocated - libhashkit Documentation

SYNOPSIS

       #include <libhashkit-1.0/hashkit.h>
              Compile and link with -lhashkit

       typedef struct hashkit_st hashkit_st

       hashkit_st *hashkit_create(hashkit_st *hash)

              Parameters
                     hash  --  memory address of a hashkit_st struct; if a nullptr is passed, the struct will be
                     dynamically allocated by libhashkit

              Returns
                     pointer to initialized hashkit_st structure

       hashkit_st *hashkit_clone(hashkit_st *destination, const hashkit_st *ptr)

              Parameters

                     • destination -- memory address of a hashkit_st struct; if a nullptr is passed, the  struct
                       will be dynamically allocated by libhashkit

                     • ptr -- pointer of the hashkit_st struct to copy

              Returns
                     pointer to a hashkit_st structure (destination, if not nullptr), initialized from ptr

       void hashkit_free(hashkit_st *hash)

              Parameters
                     hash -- pointer to an initialized hashkit_st struct

       bool hashkit_is_allocated(const hashkit_st *hash)

              Parameters
                     hash -- pointer to an initialized hashkit_st struct

              Returns
                     bool, whether the hash struct was dynamically allocated

DESCRIPTION

       The  hashkit_create()  function  initializes a hashkit object for use. If you pass a nullptr argument for
       hash, then the memory for the object is allocated. If you specify a pre-allocated piece of  memory,  that
       is initialized for use.

       The  hashkit_clone()  function  initializes  a  hashkit object much like hashkit_create(), but instead of
       using default settings it will use the settings of the ptr hashkit object.

       The hashkit_free() frees any resources being consumed by the hashkit objects that were  initialized  with
       hashkit_create() or hashkit_clone().

       The hashkit_is_allocated() reports whether the memory was allocated for a hashkit object.

RETURN VALUE

       hashkit_create() and hashkit_clone() will return nullptr on failure or pointer to hashkit_st on success.

       hashkit_is_allocated()  returns  true  if  the  memory  for  the  hashkit  object was allocated inside of
       hashkit_create() or hashkit_clone(), otherwise it is false and was user-supplied memory.
