sstr_t ucx_asprintf	(	UcxAllocator *	allocator,
		const char *	fmt,
			...
	)

universe@390:

universe@390: universe@390:

A printf() like function which allocates space for a sstr_t the result is written to.

universe@390:

Attention: The sstr_t data is allocated with the allocators ucx_allocator_malloc() function. So it is implementation dependent, if the returned sstr_t.ptr pointer must be passed to the allocators ucx_allocator_free() function manually.

universe@390:

Note: The sstr_t.ptr of the return value will always be NULL-terminated.

universe@390:

Parameters

universe@390: universe@390: universe@390: universe@390: universe@390:

allocator	the UcxAllocator used for allocating the result sstr_t
fmt	format string
...	additional arguments

universe@390:

Returns: a sstr_t containing the formatted string
