27 // -----------------------------------------------------------------------------
28 // Funcation name: mmap
29 // Description: Provides mmap functionality.
30 // Returns: valid address : On success
32 // In case of error, errno value set
34 // -----------------------------------------------------------------------------
36 EXPORT_C void* mmap(void */*addr*/, size_t len, int prot, int flags, int fildes, off_t offset)
38 //TODO;To validate addr for page boundry and sharedmemory
39 return _mmap_r(_REENT, len, prot, flags, fildes, offset);
42 // -----------------------------------------------------------------------------
43 // Funcation name: munmap
44 // Description: Provides munmap functionality.
45 // Returns: 0 : On success
47 // In case of error, errno value set
48 // Remark: support for unmapping part of the mapped pages is not supported
49 // Unmap will remove all mappings those were mapped starting from the offset
50 // to offset + len (refer to mmap signature)

75 // Description: Provides msync functionality.
