Simplified allocation function that allocates the specified number of elements of the given type.
It also explicitly casts it to the requested type.
T | the type of the variable(s) to allocation. |
num_elements | the number of elements to allocate of the given type. |

element_size | Size of the structure to allocate. |
num_elements | Number of elements to allocate. |

inline |
Simplified reallocation function that allocates the specified number of elements of the given type.
It also explicitly casts it to the requested type. It extends/shrinks the memory allocation given in t_ptr.
T | the type of the variable(s) to allocation. |
t_ptr | the previous allocation to extend/shrink. |
num_elements | the number of elements to allocate of the given type. |
