Memory

The memory system in Kore for heap allocation is based on pools. At startup Kore will initialize at least 10 pools for commonly sized objects (ranging from 8 to 8192 bytes).

Any data allocated via kore_malloc(), kore_strdup() or kore_realloc() comes from the common pools unless it is larger than 8192 in which case calloc() is used.

kore_malloc

Synopsis

void *kore_malloc(size_t length)

Description

Allocates new data.

Parameter Description
length The length of the data to allocate.

Returns

A pointer to allocated memory that can hold length bytes. The returned pointer is aligned for use with any data type.

Description

Allocates new data and zeroes it out.

Parameter Description
memb Number of objects.
len Size of each object.

Returns

A pointer to allocated memory that can hold memb * len bytes. The returned pointer is aligned for use with any data type and the contents is zeroed out.


kore_realloc

Synopsis

void *kore_realloc(void *ptr, size_t length)

Description

Grows or shrinks an existing allocated memory pointer.

Parameter Description
ptr The pointer to reallocate.
length The new length of the data.

Returns

A pointer to the newly allocated memory.


kore_free

Synopsis

void kore_free(void *ptr)

Description

Frees a previously allocated pointer.

Parameter Description
ptr The pointer to be freed.

Returns

Nothing
