vector.h

C header library for typed lists (using macros and "template" C).

Essentially, this is a resizable array of elements of your choosing that is automatically managed by a few simple functions.

Similar in spirit to sort.h.

Instructions

Download vector.h and put it somewhere in your -I include path.

Define the VECTOR_TYPE macro with the type you want your vector to be of. Like, int, float, etc.

Define the VECTOR_NAME to be the "name" of the vector type, in that, all functions will look like vec_VECTOR_NAME_somefun. (See below.)

#include "vector.h"

For example, if your VECTOR_NAME is int, then you now have vec_int_t as your type. You can pass them around normally as value types, but you always need to init them.

vec_int_t myvec;
vec_int_init(myvec);

You also have access to all the functions you need, including:

• init (initialize an vec_whatever_t)
• get
• pop (remove and return the last element)
• del (delete an element anywhere in the vector; WARNING: could rewrite the whole list.)
• size
• append

Sample usage

#include <stdio.h>
#define VECTOR_TYPE int
#define VECTOR_NAME int
#include "vector.h"

int main(void) {
  int i;
  vec_int_t vec;
  vec_int_init(vec);
  vec_int_append(vec, 2);
  vec_int_append(vec, 100);
  vec_int_pop(vec);
  vec_int_del(vec, 0);

  for (i = 0; i < vec_int_size(vec); i++) {
    printf("%d\n", vec_int_get(vec, i));
  }
}
