Typedef Documentation

typedef struct mem_stat_t mem_stat_t

/struct mem_stat_t /brief Struct for Memory stats Buffer structure

Enumeration Type Documentation

enum heap_fail_t

Dynamically heap system failure call back event types.

Enumerator:
NS_DYN_MEM_NULL_FREE 

ns_dyn_mem_free(), NULL pointer free [obsolete - no longer faulted]

NS_DYN_MEM_DOUBLE_FREE 

ns_dyn_mem_free(), Possible double pointer free

NS_DYN_MEM_ALLOCATE_SIZE_NOT_VALID 

Allocate size is 0 or smaller or size is bigger than max heap size.

NS_DYN_MEM_POINTER_NOT_VALID 

ns_dyn_mem_free(), try to free pointer which not at heap sector

NS_DYN_MEM_HEAP_SECTOR_CORRUPTED 

Heap system detect sector corruption.

NS_DYN_MEM_HEAP_SECTOR_UNITIALIZED 

ns_dyn_mem_free(), ns_dyn_mem_temporary_alloc() or ns_dyn_mem_alloc() called before ns_dyn_mem_init()

Definition at line 35 of file nsdynmemLIB.h.

Function Documentation

void* ns_dyn_mem_alloc ( int16_t  alloc_size )

Allocate long period data.

Space allocate started from end of the heap sector

Parameters:
alloc_sizeAllocated data size
Returns:
0, Allocate Fail
>0, Pointer to allocated data sector.

Definition at line 18 of file FEATURE_COMMON_PAL/nanostack-hal-mbed-cmsis-rtos/cs_nvm/test/test_cs_nvm_unit/unittest/stubs/nsdynmemLIB_stub.c.

void ns_dyn_mem_free ( void *  heap_ptr )

Free allocated memory.

Parameters:
heap_ptrPointer to allocated memory
Returns:
0, Free OK
<0, Free Fail

Definition at line 44 of file FEATURE_COMMON_PAL/nanostack-hal-mbed-cmsis-rtos/cs_nvm/test/test_cs_nvm_unit/unittest/stubs/nsdynmemLIB_stub.c.

const mem_stat_t* ns_dyn_mem_get_mem_stat ( void   )

Get pointer to the current mem_stat_t set via ns_dyn_mem_init.

Get pointer to the statistics information, if one is set during the initialization. This may be useful for statistics collection purposes.

Note: the caller may not modify the returned structure.

Returns:
NULL, no mem_stat_t was given on initialization
!=0, Pointer to mem_stat_t.

Definition at line 108 of file nsdynmemLIB.c.

void ns_dyn_mem_init ( uint8_t *  heap,
uint16_t  h_size,
void(*)(heap_fail_t)  passed_fptr,
mem_stat_t *  info_ptr 
)

Init and set Dynamical heap pointer and length.

Parameters:
heap_ptrPointer to dynamically heap buffer
heap_sizesize of the heap buffer
Returns:
None

Definition at line 14 of file FEATURE_COMMON_PAL/nanostack-hal-mbed-cmsis-rtos/cs_nvm/test/test_cs_nvm_unit/unittest/stubs/nsdynmemLIB_stub.c.

void* ns_dyn_mem_temporary_alloc ( int16_t  alloc_size )

Allocate temporary data.

Space allocate started from beginning of the heap sector

Parameters:
alloc_sizeAllocated data size
Returns:
0, Allocate Fail
>0, Pointer to allocated data sector.
