## Macro Definition Documentation

## ckd_calloc

#define ckd_calloc | ( |  | n,
|  |  | sz
| ) |  | __ckd_calloc__((n),(sz),__FILE__,__LINE__)

Macros to simplify the use of above functions.

One should use these, rather than target functions directly. Macro for ckd_calloc

## Function Documentation

## __ckd_calloc_2d__()

SPHINXBASE_EXPORT void* __ckd_calloc_2d__ | ( | size_t | d1,
|  | size_t | d2,
|  | size_t | elemsize,
|  | const char * | caller_file,
|  | int | caller_line
| ) |  |

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.

Definition at line 220 of file ckd_alloc.c.

## __ckd_calloc_3d__()

SPHINXBASE_EXPORT void* __ckd_calloc_3d__ | ( | size_t | d1,
|  | size_t | d2,
|  | size_t | d3,
|  | size_t | elemsize,
|  | const char * | caller_file,
|  | int | caller_line
| ) |  |

Allocate a 3-D array and return ptr to it.

The data area is allocated in one block so it can also be treated as a 1-D array.

Definition at line 262 of file ckd_alloc.c.

## __ckd_calloc_4d__()

SPHINXBASE_EXPORT void**** __ckd_calloc_4d__ | ( | size_t | d1,
|  | size_t | d2,
|  | size_t | d3,
|  | size_t | d4,
|  | size_t | elem_size,
|  | char * | caller_file,
|  | int | caller_line
| ) |  |

Allocate a 34D array and return ptr to it.

The data area is allocated in one block so it can also be treated as a 1-D array.

Definition at line 307 of file ckd_alloc.c.

## ckd_set_jump()

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.

Parameters

  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().

Returns
  Pointer to a previously set `jmp_buf`, if any.
