What is the difference between the various unistd.h under /usr/include in Linux ?
- by Marwan
Under the /usr/include directory in Linux i entered the command:
find -type f -name unistd.h which gave the following output:
./unistd.h
./linux/unistd.h
./asm-generic/unistd.h
./bits/unistd.h
./asm/unistd.h
./sys/unistd.h
my question is, what is the purpose of each unistd.h, since there is only one definiton of that file in the single unix specification ?
Thanks in advance.
