NAME
mman.h, mman - memory management declarations SYNOPSIS
#include <sys/mman.h> DESCRIPTION
The <sys/mman.h> header supports the following options: o the Memory Mapped Files option o the Shared Memory Objects option o the Process Memory Locking option o the Memory Protection option o the Synchronized Input and Output option For Memory Mapped Files and Shared Memory Objects options, the following protection options are defined: PROT_READ Page can be read. PROT_WRITE Page can be written. PROT_EXEC Page can be executed. PROT_NONE Page cannot be accessed. The following flag options are defined: MAP_SHARED Share changes. MAP_PRIVATE Changes are private. MAP_FIXED Interpret addr exactly. The flags immediately following are defined for msync(). See msync(3C). MS_ASYNC Perform asynchronous writes. MS_SYNC Perform synchronous writes. MS_INVALIDATE Invalidate mappings. The symbolic constants immediately following are defined for the mlockall() function. See mlockall(3C). MCL_CURRENT Lock currently mapped pages. MCL_FUTURE Lock pages that become mapped. The symbolic constant MAP_FAILED is defined to indicate a failure from the mmap() function. See mmap(2). The mode_t, off_t, and size_t types are be defined as described in <sys/types.h>. See types(3HEAD). ATTRIBUTES
