Control: retitle -1 ltrace: [p]{read,write}[v]() handling, common *64()
functions in modern glibc, [fl]seek[o]()/ftell[o](); requisite [u]llong; 20x
speed optimisation in default config; format %b+bin() lens and %w[f]32x
Attaching (a) a fix for the pre-mapping patch that broke misaligned
accesses instead of unbreaking them (sorry), and (b) format %b (already
in bookworm glibc but now standard in C2x) + a free bin() lens,
and (c) format %w[f]{digits}[formatspec] (new in C2x, glibc 2.38).
Thus (with a ltrace.conf that has "long write(int, string3, bin(ulong))":
$ cat qwe.c
int main() {
printf("%#b\n", 69);
printf("%w64x %s\n", "gameing", (char *)0);
write(1, "zupa\n", 5);
}
$ ./ltrace -F ./ltrace.conf ./qwe | tail
printf("%#b\n", 0b1000101) = 10
printf("%w64x %s\n", 0x563ab86eb013, nil) = 14
write(1, "zupa\n", 0b101) = 5
+++ exited (status 0) +++
zupa
0b1000101
%w64x gameing
