Support Functions 3
Example
A code example below shows how to use the ippGetStatusString function. If you call an Intel IPP function,
in this example ippiSet_8u_C1R, with a NULL pointer, it returns an error code -8.
void statusInfo( void ) {
}
IppiSize roi = {0};
IppStatus st = ippiSet_8u_C1R(3, 0, 0, roi );
printf( " %d : %s\n", st, ippGetStatusString( st ));
Output:
-8, Null Pointer Error
Memory Allocation Functions
This section describes the Intel IPP functions that allocate aligned memory blocks for data of required type,
or free previously allocated memory.
NOTE
The only function to free the memory allocated by any of these functions is ippiFree().
Malloc
Allocates memory aligned to 64-byte boundary.
Syntax
Case 1: Memory allocation for blocks of 32-bit sizes
