(char const * string
This function will convert one input string into a list of strings. The list of
strings is derived by separating the input based on white space separation.
However, if the input contains either single or double quote characters, then
the text after that character up to a matching quote will become the string in
The returned pointer should be deallocated with free(3C)

using the data. The data are placed in a single block of allocated memory. Do
not deallocate individual token/strings.
The structure pointed to will contain at least these two fields:
The number of tokens found in the input string.
An array of tkn_ct + 1
pointers to substring tokens, with
the last pointer set to NULL.
There are two types of quoted strings: single quoted ( '
) and double
quoted ( "
). Singly quoted strings are fairly raw in that escape
characters ( \
) are simply another character, except when preceding the
\ double backslashes reduce to one
' incorporates the single quote into the string
0fP suppresses both the backslash and newline character
Double quote strings are formed according to the rules of string constants in
- string to be tokenized
pointer to a structure that lists each token
NULL is returned and errno
will be set to indicate the problem:
- There was an unterminated quoted string.
- The input string was empty.
- There is not enough memory. @end itemize
