Allocate a 2-D array and return ptr to it (ie, ptr to vector of ptrs).
The data area is allocated in one block so it can also be treated as a 1-D array.

jmp_buf* ckd_set_jump | ( | jmp_buf * | env, |
int | abort | ||
) |
Control behaviour of the program when allocation fails.
Although your program is probably toast when memory allocation fails, it is also probably a good idea to be able to catch these errors and alert the user in some way. Either that, or you might want the program to call abort() so that you can debug the failed code. This function allows you to control that behaviour.
env | Pointer to a jmp_buf initialized with setjmp(), or NULL to remove a previously set jump target. |
abort | If non-zero, the program will call abort() when allocation fails rather than exiting or calling longjmp(). |
