 Name:
	PIUtil_malloc

 Synopsis:
	void *PIUtil_malloc( unsigned long lSize )
	
 Description:
	Allocate memory.	

 Notes:
	Memory allocated with PIUtil_malloc() should be freed with 
	PIUtil_free().

 Return Values:
	On success this function returns a non-NULL pointer to a memory
	area of size equal to or greater than lSize.

 Errors:
	PIUtil_malloc() returns NULL if the requested memory could not
	be allocated.

	More error information is available via PIPlatform_getLastError().

 See Also:
	PIUtil_free().

 Name:
	PIUtil_stricmp

 Synopsis:
	int PIUtil_stricmp( const char *pS1, const char *pS2 )
	
 Description:
	Compare two strings without case sensitivity.

 Notes:
	The result is undefined if either parameter is NULL.

 Return Values:
	This function returns the following values

	<ul compact>
		<li>&gt; 0 if pS1 is lexigraphically greater than pS2
		<li>&lt; 0 if pS2 is lexigraphically greater than pS1
		<li>0 if both strings are lexigraphically equivalent
	</ul>

 Errors:
	There are no error return codes from this function.

 Description:
	Compare two strings without case sensitivity up to iLen characters.

 Notes:
	The result is undefined if either parameter is NULL.

 Return Values:
	This function returns the following values

	<ul compact>
		<li>&gt; 0 if pS1 is lexigraphically greater than pS2<BR>
		<li>&lt; 0 if pS2 is lexigraphically greater than pS1<BR>

 Name:
	PIUtil_strdup

 Synopsis:
	char *PIUtil_strdup( const char *pS )
	
 Description:
	Duplicate a NULL terminated character array.

 Notes:
	The function PIUtil_free() should be used to deallocate memory
	allocated via PIUtil_strdup().

 Return Values:
	On success PIUtil_strdup returns a copy of the character array
	pS.

 Errors:
	On error PIUtil_strdup() returns NULL.
	More information is available via PIPlatform_getLastError().

 Name:

 Synopsis:
	void PIUtil_free( void *pV )
	
 Description:
	Deallocate memory allocated by another function with the PIUtil_
	prefix.

 Notes:

 Return Values:
	PIUtil_free() does not return a value.

 Errors:
	None.
