+FUNCTION
+	<<strtok>>---get next token from a string
+
+INDEX
+	strtok

+INDEX

+
+ANSI_SYNOPSIS
+	#include <string.h>
+      	char *strtok(char *<[source]>, const char *<[delimiters]>)
+      	char *strtok_r(char *<[source]>, const char *<[delimiters]>,
+			char **<[lasts]>)
+
+TRAD_SYNOPSIS
+	#include <string.h>
+	char *strtok(<[source]>, <[delimiters]>)
+	char *<[source]>;
+	char *<[delimiters]>;
+
+	char *strtok_r(<[source]>, <[delimiters]>, <[lasts]>)
+	char *<[source]>;
+	char *<[delimiters]>;
+	char **<[lasts]>;
+
+DESCRIPTION
+	The <<strtok>> function is used to isolate sequential tokens in a 
+	null-terminated string, <<*<[source]>>>. These tokens are delimited 
+	in the string by at least one of the characters in <<*<[delimiters]>>>.
+	The first time that <<strtok>> is called, <<*<[source]>>> should be
+	specified; subsequent calls, wishing to obtain further tokens from
+	the same string, should pass a null pointer instead.  The separator
+	string, <<*<[delimiters]>>>, must be supplied each time, and may 
+	change between calls.
+
+	The <<strtok>> function returns a pointer to the beginning of each 
+	subsequent token in the string, after replacing the separator 
+	character itself with a NUL character.  When no more tokens remain, 
+	a null pointer is returned.
+
+	The <<strtok_r>> function has the same behavior as <<strtok>>, except
+	a pointer to placeholder <<*[lasts]>> must be supplied by the caller.
+
+RETURNS
+	<<strtok>> returns a pointer to the next token, or <<NULL>> if
+	no more tokens can be found.
+
+NOTES
+	<<strtok>> is unsafe for multi-thread applications.  <<strtok_r>>
+	is MT-Safe and should be used instead.
+
+PORTABILITY
+<<strtok>> is ANSI C.
+
+<<strtok>> requires no supporting OS subroutines.
