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().

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
> 0 if pS1 is lexigraphically greater than pS2
< 0 if pS2 is lexigraphically greater than pS1
0 if both strings are lexigraphically equivalent
Errors:
There are no error return codes from this function.
