New Memory Block Functions

The following new memory block functions are defined:

New Memory Allocation Function

CRE has a new memory allocation function: malloc_pages(). The behavior of

malloc_pages is the same as malloc(), except that the allocated memory is automatically

aligned to a page boundary. The number of bytes requested for the space is rounded

up to a multiple of the page size so that the allocated space always occupies one or

more complete pages.

Developing TNS/R Native Programs on

H-Series Systems

Beginning with the H06.05 RVU, TNS/R development tools are supported on H-series

systems. Using these tools, you can compile and link TNS/R native programs on an

H-series system, then transfer the object files to a G-series system for execution. The

TNS/R object files cannot be executed on an H-series system. You can, however, use

Visual Inspect on a TNS/E system to debug TNS/R snapshot files produced on a

TNS/R platform. Table 2-6 shows the TNS/R tools that are available on H-series

systems.

wmemchr Searches for a wide character in a block of memory

wmemcmp Compares two blocks of wide-character memory

wmemcpy Copies a block of wide-character memory

wmemmove Moves a block of wide-character memory

wmemset Initializes a block of wide-character memory to a specified character

value
