Vectors

struct vec

void* st

• points to start of vector.

size_t sizeoft

• size of each element in vector.

size_t count

• count of elements present in vector

struct vec vector_new(size_t vec_size)

usage

Creates a new vector with elements of size size_t vec_size

params

size_t vec_size - sizeof type of elements

returns

vec struct with void* st set to NULL

void* vector_get(struct vec* vec, size_t index)

usage

Returns element at index in vector

params

struct vec* vec - the vector to perform operation on size_t index - the index of the element to retrieve

returns

void* to the element inside the vector

void vector_push(struct vec* vec, void* el)

usage

• Pushes element at the end of vector.
• If not enough space allocated allocates VECTOR_STEP * vec->sizeoft more bits using realloc().

params

struct vec* vec - the vector to perform operation on void* el - pointer to an element to be pushed at the end of vector

```void vector_pop(struct vec* vec, void* dest)

usage

• Copies element at end of vector into void* dest.
• Deallocates memory in steps of VECTOR_STEP elements.

params

struct vec* vec - the vector to perform operation on void* dest - location in which to copy the result of the pop

void vector_free(struct vec* vec)

usage

• Frees allocated memory at vec->st

params

struct vec* vec - the vector to perform operation on

bool vector_is_empty(struct vec* vec)

usage

• Check if vector is empty

params

struct vec* vec - the vector to perform operation on

returns

bool - Whether ot not the vector has any elements in it
