Function Documentation

◆ otPlatCAlloc()

void* otPlatCAlloc ( size_t aNum,
size_t aSize
)

Dynamically allocates new memory.

On platforms that support it, should just redirect to calloc. For those that don't support calloc, should support the same functionality:

"The calloc() function contiguously allocates enough space for count objects that are size bytes of memory each and returns a pointer to the allocated memory. The allocated memory is filled with bytes of value zero."

This function is available and can ONLY be used only when support for multiple OpenThread instances is enabled.

Parameters
[in] aNum The number of blocks to allocate
[in] aSize The size of each block to allocate
Return values
void* The pointer to the front of the memory allocated
NULL Failed to allocate the memory requested.

◆ otPlatFree()

void otPlatFree ( void * aPtr )

Frees memory that was dynamically allocated.

This function is available and can ONLY be used only when support for multiple OpenThread instances is enabled.

Parameters
[in] aPtr A pointer the memory blocks to free. The pointer may be NULL.
