** SM_STRINGF_X -- printf() to dynamically allocated string.

**
|
|
** Takes the same arguments as printf.

** It returns a pointer to a dynamically allocated string

** containing the text that printf would print to standard output.
|
|
** It raises an exception on error.
|
|
** The name comes from a PWB Unix function called stringf.

|
|
** Parameters:
|
|
** fmt -- format string.
|
|
** ... -- arguments for format.

|

** Returns:
|
|
** Pointer to a dynamically allocated string.

** Exceptions:

** F:sm_heap -- out of memory (via sm_vstringf_x()).
