## Typedefs
typedef void *(* | rpmMemFailFunc) (size_t size, void *data)

## Functions
rpmMemFailFunc | rpmSetMemFail (rpmMemFailFunc func, void *data)

## Detailed Description

Miscellaneous utility APIs.

## Typedef Documentation

## ◆ rpmMemFailFunc

typedef void *(* rpmMemFailFunc) (size_t size, void *data)

Memory allocation failure callback prototype. When registered through rpmSetMemFail(), this gets called if memory allocation through rmalloc() and friends fails. If the application can somehow recover memory here, it can return a newly allocated memory block of requested size, otherwise it must return NULL after performing it's own shutdown deeds or terminate itself.

Parameters

  size | Size of allocation request in bytes
  data | User data (or NULL)

Returns
  Allocated memory block of requested size or NULL

## Function Documentation

## ◆ rpmSetMemFail()

rpmMemFailFunc rpmSetMemFail | ( | rpmMemFailFunc | func,
|  | void * | data )

Set memory allocation failure callback.

Parameters

  func | Allocation failure callback function
  data | User data (or NULL)

Returns
  Previous callback function
