ado_calloc()

Allocate space for an array

Synopsis:

#include <audio_driver.h>

void *ado_calloc( size_t n,
                  size_t size );

Arguments:

n
The number of elements to allocate in the array.
size
The size of each element.

Description:

The ado_calloc() macro allocates space from the heap for an array.

This macro is defined as ado_calloc_debug(), or calloc(), if ADO_DEBUG is defined; see Debugging an audio driver in the Organization of a Driver chapter.

The advantage of using the debug variant is that it tracks the memory allocated until it's freed; see ado_memory_dump().

Returns:

The same as calloc(): a pointer to the start of the allocated memory, or NULL if there's insufficient memory available or if size is zero.

Classification:

QNX Neutrino

Safety:
Cancellation point No
Interrupt handler No
Signal handler No
Thread Yes
