Add Realloc and Calloc

Posted by enrico_entity on November 23, 2005
Is it possible to add in future release realloc and calloc function? It is sufficient to add this code:

void *pvPortCalloc( size_t nmemb, size_t size )
{
void *pvReturn;

vTaskSuspendAll();
{
pvReturn = calloc( nmemb, size );
}
xTaskResumeAll();

return pvReturn;
}


void *pvPortRealloc( void *pv, size_t size )
{
void *pvReturn;

vTaskSuspendAll();
{
pvReturn = realloc( pv, size );
}
xTaskResumeAll();

return pvReturn;
}

in heap_3.c source file and add these declarations:

void *pvPortCalloc( size_t nmemb, size_t size );
void *pvPortRealloc( void *pv, size_t size );

in portable.h header file.

Thank you.

The memory schemes are just examples. The prototypes should be included in the header, this way users can add your code if they wish. It would be harder for the heap_1 and heap_2 schemes.
