       strtrim - remove leading and trailing whitespace

SYNOPSIS
       #include <publib.h>
       char *strtrim(char *s);

DESCRIPTION
       strtrim removes all whitespace characters from the beginning and the
       end of a string.  As whitespace is counted everything for which
       isspace(3) returns true.

EXAMPLE
       To remove whitespace from the beginning and end of all lines, you might
       do the following:

            #include <publib.h>

            int main(void) {
                 char line[512];

                 while (fgets(line, sizeof(line), stdio) != NULL) {
                      strtrim(line);
                      printf("%s", line);
                 }
                 return 0;
            }
