Detailed Description

Macro Definition Documentation

#define IPC_ALLOC ( var ) ipc_malloc(sizeof(*var))

Allocate dynamic IPC memory for a typed pointer var.

1 struct ua_string *s = IPC_ALLOC(s);

#define IPC_ALLOC_ARRAY	(	var,
		num
	)	ipc_malloc(sizeof(var)(num))

Allocate array of dynamic IPC memory for a typed pointer var.

 uint32_t *x = IPC_ALLOC_ARRAY(x, 2);
 if (x == NULL) goto error;
 x[0] = 35;
 x[1] = 43;

#define IPC_CALLOC ( var ) ipc_calloc(1, sizeof(*var))

Allocate zero initialized dynamic IPC memory for a typed pointer var.

#define IPC_CALLOC_ARRAY	(	var,
		num
	)	ipc_calloc(num, sizeof(*var))

Allocate zero initialized array of dynamic IPC memory for a typed pointer var.

#define IPC_CLEANUP_MEM_ON_ERROR	(	ret,
		ptr
	)

Value:

if (ret != 0) { \
        ipc_free(ptr); \
        ptr = NULL; \
    }

On error (ret != 0) free dynamic IPC memory and set pointer to NULL.

#define IPC_FREE ( var ) ipc_free(var)

Free dynamic memory from IPC memory.

#define size_align	(	size,
		alignment
	)	(((size) + (alignment) - 1) / (alignment) * (alignment))

This rounds up the given size to a multiple of alignment.

Function Documentation

char* ipc_strdup ( const char * s )

String duplication using ipc_malloc.

Behaves like the original strdup(), but allocates new memory with ipc_malloc.

void* pointer_align ( void * ptr )

This rounds up the given address to next valid aligned pointer address.
