.SH DESCRIPTION
The \fB@LISTHASH_PREFIX@_list_new\fP() function creates a new list. The \fIflags\fP
argument must be one of the following values:
.IP \fBLIST_USERFUNC\fP
The \fIcmpfunc\fP argument points to a user-supplied function which
determines the ordering of the list.
.IP \fBLIST_STACK\fP
Use the list as a stack. New elements are added to the front of the list.
.IP \fBLIST_QUEUE\fP
Use the list as a queue. New elements are added to the end of the list.
.PP
The \fB@LISTHASH_PREFIX@_list_free\fP() function deallocates all memory associated
with the list \fIl\fP. If \fIfreefunc\fP is not \fINULL\fP, it is called
to free memory associated with each node in the list.
The \fB@LISTHASH_PREFIX@_list_add\fP() function adds the element pointed to by
\fIdata\fP to the list \fIl\fP. The position of the new element will
be determined by the flags passed to \fB@LISTHASH_PREFIX@_list_new\fP() when the
list was created.
The \fB@LISTHASH_PREFIX@_list_add_str\fP() function tokenizes the string \fIstr\fP
using the delimiter characters in the string \fIdelim\fP. The resulting
tokens are added to list \fIl\fP using \fB@LISTHASH_PREFIX@_list_add\fP().
The \fB@LISTHASH_PREFIX@_list_search\fP() function searches for an element which
matches \fIdata\fP using the matching function \fImatchfunc\fP. If
\fImatchfunc\fP is \fINULL\fP, a default matching function designed for
ASCII strings is used. Searching begins from the node pointed to by
\fIn\fP.
The \fB@LISTHASH_PREFIX@_list_del\fP() function removes the entry pointed to by
\fIn\fP from the list pointed to by \fIl\fP.
The \fB@LISTHASH_PREFIX@_list_dup\fP() function creates a copy of the list \fIl\fP
using dynamically allocated memory.
The \fB@LISTHASH_PREFIX@_list_merge\fP() function creates a new
list with \fIflags\fP and \fIcmpfunc\fP, in the same way as
\fB@LISTHASH_PREFIX@_list_new\fP(). It then adds all elements from \fIlist1\fP
and \fIlist2\fP using \fB@LISTHASH_PREFIX@_list_add\fP().
.SH RETURN VALUE
The \fB@LISTHASH_PREFIX@_list_new\fP(), \fB@LISTHASH_PREFIX@_list_dup\fP(), and
\fB@LISTHASH_PREFIX@_list_merge\fP() functions return a pointer to the new list
structure, or \fINULL\fP on error.
The \fB@LISTHASH_PREFIX@_list_next\fP(), \fB@LISTHASH_PREFIX@_list_prev\fP(), and
\fB@LISTHASH_PREFIX@_list_search\fP() functions return 1 when valid data is
returned, or 0 otherwise.
The \fB@LISTHASH_PREFIX@_list_add\fP() and \fB@LISTHASH_PREFIX@_list_add_str\fP() functions
return 0 on success, or -1 on error.
