NAME
CsrPmemAlloc
DESCRIPTION
This function will allocate a contiguous block of memory of at least
the specified size in bytes and return a pointer to the allocated
memory. This function is not allowed to return NULL. A size of 0 is a
valid request, and a unique and valid (not NULL) pointer must be
returned in this case.
PARAMETERS
size - Size of memory requested. Note that a size of 0 is valid.
RETURNS
Pointer to allocated memory.
