This appears to have been in the code for a while, and it's a minor warning,
but I thought I'd mention it.
gcc -c -I. -Iproto -DHAVE_CONFIG_H -O2 -Wall -Wextra -pipe -std=gnu99
-DNDEBUG -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1 -o objects/misc2.o misc2.c
misc2.c: In function 'put_time':
misc2.c:6289: warning: ignoring return value of 'fwrite', declared with
attribute warn_unused_result
Looking at the code in question, we should probably be checking the return
value of fwrite, but I'm not sure what the "best" solution would be to handle
an error writing 8 bytes to the file handle.
My suggestion would be to make this a non-void function.
Here's the code in question with line numbers:
src/misc2.c
6278 /*
6279 * Write time_t to file "fd" in 8 bytes.
6280 */
6281 void
6282 put_time(fd, the_time)
6283 FILE^I*fd;
6284 time_t^Ithe_time;
6285 {
6286 char_u^Ibuf[8];
6287
6288 time_to_bytes(the_time, buf);
6289 fwrite(buf, (size_t)8, (size_t)1, fd);
6290 }
