Firestring_vfprintf(3) with an estring format
#include <firestring.h>
-lfirestring
long firestring_vfprintfe(FILE * stream, struct firestring_estr_t *format, va_list ap)
firestring_vfprintfe() behaves exactly like firestring_vfprintf(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.
