firestring_estr_vsprintf(3)
SYNOPSIS
#include <firestring.h>
-lfirestring
long firestring_estr_vsprintfe(struct firestring_estr_t *out, struct firestring_estr_t *format, va_list ap)
DESCRIPTION
firestring_estr_vsprintfe() behaves exactly like
firestring_estr_vsprintf(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.
RETURN VALUE
Returns the number of bytes written to
out.
