strfry<\/h3>\n

The function below addresses the perennial programming quandary: “How do
\nI take good data in string form and painlessly turn it into garbage?”
\nThis is actually a fairly simple task for C programmers who do not use
\nthe GNU C library string functions, but for programs based on the GNU C
\nlibrary, the strfry<\/code> function is the preferred method for
\ndestroying string data.<\/p>\n

The prototype for this function is in string.h<\/code>.<\/p>\n\n\n
char * strfry<\/b> (char *string)
\n<\/i><\/td>\n		Function<\/td>\n<\/tr>\n<\/table>\n\n\n
\n

strfry<\/code> creates a pseudorandom anagram of a string, replacing the
\ninput with the anagram in place. For each position in the string,
\nstrfry<\/code> swaps it with a position in the string selected at random
\n(from a uniform distribution). The two positions may be the same.\n<\/p>\n

The return value of strfry<\/code> is always string<\/var>.\n<\/p>\n

Portability Note:<\/strong> This function is unique to the GNU C library.\n<\/p>\n<\/td>\n<\/tr>\n<\/table>\n
