* Routines to reverse a file, char by char. *-* by C.B. Falconer, 19 Dec. 2001 *-* Released to public domain. Attribution appreciated *

* Known bugs - A file without an initial empty line *-* will have one added. *

#define MAXLN 256

typedef struct line { char *ln; struct line *next; } line, *lineptr;

* ======================================= *-* reverse string in place. Return length *sizet revstring(char *string) { char *last, temp; sizet lgh;

lgh = strlen(string); last = string + lgh; * points to '-0' * temp = *string; *string++ = *last; *last = temp; } return lgh; }* revstring *

* ========================= *-* Reverse file, end to end *int main(void) { char bufferMAXLN; lineptr p, last; sizet lgh;

p = last = NULL; while (fgets(buffer, MAXLN, stdin)) { lgh = revstring(buffer); if (p = malloc(sizeof (line))) { last = p; } else { free(p); break; } } else break; } p = NULL; while (last) { free(p); p = last; } fputc('-n', stdout); free(p); return 0; }* main *
