Change the second strtok() example on P2041, L64687-64702 from:
    <bold>Breaking a Lina</bold>e

    The following example uses strtok() to break a line into two
    character strings separated by any combination of <space>,
    <tab>, or <newline> characters.

    #include <string.h>
    ...
    struct element {
        char *key;
        char *data;
    };
    ...
    char line[LINE_MAX];
    char *key, *data;
    ...
    key = strtok(line, " \n");
    data = strtok(NULL, " \n");
    ...
to:
    <bold>Find first two fields in a buffer</bold>

    The following example uses strtok() to find two character strings
    (a key and data associated with that key) separated by any
    combination of <space>, <tab>, or <newline> characters at the
    start of the array of characters pointed to by buffer.
         
    #include <string.h>
    ...
    char    *buffer;
    ...
    struct element {
        char    *key;
        char    *data;
    } e;
    ...
    // Load tbe buffer...
    ...
    // Get the key and its data...
    e.key = strtok(buffer, " \t\n");
    e.data = strtok(NULL, " \t\n");
    // Process the rest of the contents of the buffer...
    ...
