Is there an option, part of read() that when calling read() on a file descriptor it only prints out the characters up to the null terminator?

Sorry, no, there isn’t.
read()doesn’t look at the data at all; it just reads as many bytes as there are (but not more than your buffer size).I would do this with the higher-level
stdio.hfunctions, by callinggetc()(and writing to a buffer) until I saw a NUL byte, and thenungetc()on the NUL.
