Firestring_estr_sprintf(3) with an estring format
#include <firestring.h>
-lfirestring
long firestring_estr_sprintfe(struct firestring_estr_t *out, struct firestring_estr_t *format, ...)
firestring_estr_sprintfe() behaves exactly like firestring_estr_snprintf(3) except that it takes an estring format argument, so the format can contain arbitrary binary data. However, please note that user user-input data as the format string is INSECURE.
Returns the number of bytes written to out.
