Publib                                        C Programmer's Manual                                 STRDEL(3pub)

strdel  removes  the  first  n  characters  of  s.   If  n  is greater than the length of the string, all
       characters in the string (not counting '\0') are removed but no more.

       To change all occurrences of "Pascal" in the input to "Yuck!", you might do the following:

            #include <string.h>
            #include <stdio.h>
            #include <publib.h>

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

                 while (fgets(line, sizeof(line), stdio) != NULL) {
                      while ((p = strstr(line, "Pascal")) != NULL) {
                           strdel(p, 6);
                           strins(p, "Yuck!");
                      }
                      printf("%s", line);
                 }
                 return 0;
            }

       char *strdel(char *s, size_t n);
