Function list (Bold in this list means a function is not static)

/* t_dirbasename.c

   Demonstrate the use of dirname() and basename() to break a pathname
   into directory and filename components.

   Usage: t_dirbasename path...

   The program calls dirname() and basename() for each of the pathnames
   supplied on the command-line.
#include <libgen.h>
#include "tlpi_hdr.h"
main(int argc, char *argv[])
    char *t1, *t2;
    int j;

    for (j = 1; j < argc; j++)  {
        t1 = strdup(argv[j]);
        if (t1 == NULL)
        t2 = strdup(argv[j]);
        if (t2 == NULL)

        printf("%s ==> %s + %s\n", argv[j], dirname(t1), basename(t2));

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.
