Normally you would enter comments incrementally (file by file) if they occur only occasionally. ... All files of the current RAW_TYPE (or all files if no RAW_TYPE is specified) are found by the tool and get listed in the comment file (see below). ...

... The best way to illustrate the problem is with a few different examples. C example --------- The most well-known example exploits a common implementation of the UNIX popen() call, and affects primarily C programs. popen() allows the programmer to start up a command, and read from or write to it as if it were a file. ... Now imagine a CGI that uses popen to process user input. ... Perl Script example ------------------- Perl has the same problem with it's open command the C has with popen. ...

... To use system calls and library functions in a C program we simply call the appropriate C function (Appendix ).

All math functions such as sin(), cos(), sqrt() and random number generators - random(), seed(), lrand48(), drand48() etc. are standard math library functions. NOTE: most standard library functions will use system calls within them. ...
