fmt_strm_alloca − write multiple ASCII strings
#include <libowfat/fmt.h>
char* fmt_strm_alloca(const char *source, ...);
fmt_strm_alloca copies all leading nonzero bytes from source and following function arguments to a freshly allocated stack buffer and returns a pointer to it.
Unlink fmt_strm, fmt_strm_alloca does append \0.
Warning: Using variable size stack buffers is dangerous. If the size of the buffer is larger than the hardware page size, then it can be used to skip over the guard page and cause memory corruption. fmt_strm_alloca has a built-in limit of 100000 bytes. Use this only for trivially small strings.
If the strings do not come from a trusted place or you are not sure they are small, prefer fmt_strm_malloc instead.
