what does “%.*s” mean in printf in c
I have found the following line :
asprintf(&c, "%s%.*s", *msg_in, size * rxed, buffer)
And I want to know the meaning of %.*s
The
%.*sformat means “print a string using a field width of n characters, where n is read from the next argument”.So here, it prints
bufferwith a width ofsize * rxedcharacters. (padding with spaces if necessary)
