strtok function

+ +

+All the books that I have read, say that strtok will break a string +into tokens. This is true, but a more obvious +explanation is, that it will break a string into words. +

+
+Library:   string.h
+
+Prototype: char * strtok(char *s, const char *delim);
+
+Syntax:	   char string []="abc def ghi";
+	   char * word;
+
+	   word=strtok(string, " ");
+	   word=strtok(NULL, " ");
+
+

+ +strtok requires a string and the word delimiters, for example: + +

+
+	   word = strtok(string, " ");
+	                   A      A
+	                   |      |
+	                   |	  -------  Delimiters.
+	                   |
+	                   --------------  String to break up.
+
+

+After the first call to strtok, word will point to abc on the second +call, word will point to def +

Notes:

strtok will alter the I/P string by placing +NULLS at the delimiter +positions. A good habit is to copy +the string to a tempary string +and use the copy in the strtok call. +
+

More than one delimiter can be specified. So you could code: +

+
+	word = strtok(string, " \t;:,");
+	                         
+

You do not have to include \0 or NULL +
