/* us_xfr.h Header file for us_xfr_sv.c and us_xfr_cl.c. These programs employ a socket in /tmp. This makes it easy to compile and run the programs. However, for a security reasons, a real-world application should never create sensitive files in /tmp. (As a simple of example of the kind of security problems that can result, a malicious user could create a file using the name defined in SV_SOCK_PATH, and thereby cause a denial of service attack against this application. See Section 38.7 of "The Linux Programming Interface" for more details on this subject.) */ #include <sys/un.h> #include <sys/socket.h> #include "tlpi_hdr.h" #define SV_SOCK_PATH "/tmp/us_xfr" #define BUF_SIZE 100
Note that, in most cases, the programs rendered in these web pages are not free standing: you'll typically also need a few other source files (mostly in the lib/ subdirectory) as well. Generally, it's easier to just download the entire source tarball and build the programs with make(1). By hovering your mouse over the various hyperlinked include files and function calls above, you can see which other source files this file depends on.
