- memory advisory information
#include <sys/mman.h>intposix_madvise(void *addr,size_tlen,intadvice);
Theposix_madvise() function advises the system on the expected behavior of theapplication with respect to the data in the memory starting at addressaddr, and continuing forlen bytes. The system may use this information tooptimize handling of the specified data. Theposix_madvise() function has no effecton the semantics of access to memory in the specified range, althoughit may affect the performance of access.
The advice to be applied to the memory range is specified bytheadvice parameter and may be one of the following values:
Specifies that the application has no advice to give on its behavior with respect to the specified range. It is the default characteristic if no advice is given for a range of memory.
Specifies that the application expects to access the specified range sequentially from lower addresses to higher addresses.
Specifies that the application expects to access the specified range in a random order.
Specifies that the application expects to access the specified range in the near future.
Specifies that the application expects that it will not access the specified range in the near future.
These values are defined in<sys/mman.h>
Upon successful completion,posix_madvise() returns zero. Otherwise, an error number is returnedto indicate the error.
Theposix_madvise() function will fail if:
The value ofadvice is invalid.
Addresses in the range starting ataddr and continuing forlen bytes are partly or completely outside the range allowed for the address space of the calling process.
Theposix_madvise() function may fail if:
The value oflen is zero.
