+.TH LIBKECCAK_STATE_CREATE 3 LIBKECCAK-%VERSION%
+.SH NAME
+libkeccak_state_create - Allocate and initialise hash state
+.SH SYNOPSIS

+#include <libkeccak.h>
+.P
+libkeccak_state_t *libkeccak_state_create(const libkeccak_spec_t *\fIspec\fP);
+.fi
+.P
+Link with \fI-lkeccak\fP.
+.SH DESCRIPTION
+The
+.BR libkeccak_state_create ()
+allocates a new \fIlibkeccak_state_t*\fP with one initialised element,
+and sets the algorithm tuning parameters to those specified by \fI*spec\fP.
+.SH RETURN VALUES
+The
+.BR libkeccak_state_create ()
+function return a new allocated \fIlibkeccak_state_t*\fP
+(of one initialised element). On error, \fINULL\fP is returned
+and \fIerrno\fP is set to describe the error.
+.SH ERRORS
+The
+.BR libkeccak_state_create ()
+function may fail for any specified for the function
+.BR malloc (3).

+.TH LIBKECCAK_STATE_FAST_FREE 3 LIBKECCAK-%VERSION%
+.SH NAME
+libkeccak_state_fast_free - Destroys and deallocates a hash state without erasure
+.SH SYNOPSIS
+.LP
+.nf
+#include <libkeccak.h>
+.P
+void libkeccak_state_fast_free(libkeccak_state_t *\fIstate\fP);
+.fi
+.P
+Link with \fI-lkeccak\fP.
+.SH DESCRIPTION
+The
+.BR libkeccak_state_fast_free ()
+function releases the allocations stored in \fI*state\fP,
+and also released the allocation of \fIstate\fP.
+.PP
+The
+.BR libkeccak_state_fast_free ()
+function does not securely erase sensitive data.
+.SH RETURN VALUES
+The
+.BR libkeccak_state_fast_free ()
+function does not return any value.
+.SH ERRORS
+The
+.BR libkeccak_state_fast_free ()
+function cannot fail.
+.SH NOTES
+A double call to
+.BR libkeccak_state_fast_free ()
+will either result in a double free,
+which is must likely to crash the process,
+or free an allocation (that was created
+between the calls) that was not intended
+to be freed, resulting in undefined behaviour.
