<h1><a name="string">module: string</a></h1><p><b>Some simple string allocation and handling functions.</b><p>

This module contains functions for object-oriented handling of
const char* strings in C.  Strings can be either zero-terminated or have some 
fixed length.  The contents of the string cannot be (easily) changed.
<p>
MX_STRING is bit-copy-correct which means that a binary copy retains
proper functioning and takes over ownership of internal buffers.  The copy
source MX_STRING should not be used once the copy takes place.
<p>
Memory containing a MX_STRING can be realloc'd without affecting proper
operation.  Therefore it can be used inside a MX_VECTOR.

<p>
<p><b>Reallocate a MX_STRING</b><p>
This function changes the memory allocation of the text inside a
MX_STRING to the ones in the argumnets.  Memory is allocated using the alloc
function and the current contents of the string is copied to the newly
allocated memory.  The free function will be called when the memory
associated with the text needs to be freed.

<a name="void mx_string_set(MX_STRING* string, const char* text, int len, const MX_FREE dfree)"><code>void mx_string_set(MX_STRING* string, const char* text, int len, const MX_FREE dfree)</code></a>
<p>
<p><b>Set MX_STRING text and length</b><p>
This function sets the text, length and free function of a MX_STRING
object.  When mx_string_free() is called the free function will be called to
release the memory associated with the text.  The free parameter may be 0 in
which case no function will be called to release the text memory.  
(<a href="../include/deds/string/set.c">../include/deds/string/set.c</a>)

<p>If the len parameter is less than 0 (usually -1) then the string
	is assumed to be zero terminated.

<p><b>Construct a MX_STRING</b><p>
This function initializes a MX_STRING object.  It writes the memory
full with 0 values.  
(<a href="../include/deds/string/string.c">../include/deds/string/string.c</a>)

<p>Since a MX_STRING filled with 0 is correctly constructed then
    static instances dont necessarily have to be constructed before use.

<li>
<a name="void mx_string_free(MX_STRING* string)"><code>void mx_string_free(MX_STRING* string)</code></a>
<p>
<p><b>Destruct a MX_STRING</b><p>
This function frees a MX_STRING object.  If the associated free
will be called to release any internal memory.

<p><b>Get MX_STRING text and length</b><p>
This function return the text of the string along with the length
of the text segment.  
(<a href="../include/deds/string/text.c">../include/deds/string/text.c</a>)

<p>The len argument can be 0 in which case the length is not returned.

<p>
<p><b>Get MX_STRING length</b><p>
This function return the length of the text segment.
