Str.vasprintf

An implementation of the GNU vasprintf() function which supports positional parameters, as specified in the Single Unix Specification. This function is similar to g_vsprintf(), except that it allocates a string to hold the output, instead of putting the output in a buffer you allocate in advance.

glib/gprintf.h must be explicitly included in order to use this function.
