What generates the “text file busy” message in Unix?
...BSY);
perror("");
assert(ret == -1);
}
Compile and run:
gcc -std=c99 -o sleep.out ./sleep.c
gcc -std=c99 -o busy.out ./busy.c
./sleep.out &
./busy.out
busy.out passes the asserts, and perror outputs:
Text file busy
so we deduce that the message is hardcoded in glibc itself.
