## Detailed Description

Header file for "tool" classes used in QCA.

These classes differ from those in qca_support.h, in that they have some cryptographic relationship, and require secure memory.

Note
  You should not use this header directly from an application. You should just use `#include <QtCrypto>` instead.

## Function Documentation

## ◆ qca_secure_alloc()

QCA_EXPORT void* qca_secure_alloc | ( | int | bytes | ) |

Allocate a block of memory from the secure memory pool.

This is intended to be used when working with C libraries.

Parameters

  bytes | the number of bytes to allocate

## ◆ qca_secure_free()

QCA_EXPORT void qca_secure_free | ( | void * | p | ) |

Free (de-allocate) a block of memory that has been previously allocated from the secure memory pool.

This is intended to be used when working with C libraries.

Parameters

  p | pointer to the block of memory to be free'd

## ◆ qca_secure_realloc()

QCA_EXPORT void* qca_secure_realloc | ( | void * | p,
|  | int | bytes
| ) |  |

Resize (re-allocate) a block of memory that has been previously allocated from the secure memory pool.

Parameters

  p | pointer to the block of memory to be resized.
  bytes | the new size that is required.
