+
+((<Download|URL:ftp://moulon.inra.fr/pub/ruby/>))
+
+The Mmap class implement memory-mapped file objects
+
+=== WARNING
+=== The variables $' and $` are not available with gsub! and sub!
+
+== SuperClass
+
+Object
+
+== Included Modules
+
+* Comparable
+* Enumerable
+
+== Class Methods
+
+--- lockall(flag)
+ disable paging of all pages mapped. ((|flag|)) can be
+ ((|Mmap::MCL_CURRENT|)) or ((|Mmap::MCL_FUTURE|))
+
+--- new(file, mode = "r", protection = Mmap::MAP_SHARED, options = {})
+--- new(nil, length, protection = Mmap::MAP_SHARED, options = {})
+ create a new Mmap object
+
+ : ((|file|))
+ Pathname of the file, if ((|nil|)) is given an anonymous map
+ is created ((|Mmanp::MAP_ANON|))
+
+ : ((|mode|))
+ Mode to open the file, it can be "r", "w", "rw", "a"
+
+ : ((|protection|))
+ specify the nature of the mapping
+
+ : ((|Mmap::MAP_SHARED|))
+ Creates a mapping that's shared with all other processes
+ mapping the same areas of the file.
+ The default value is ((|Mmap::MAP_SHARED|))
+
+ : ((|Mmap::MAP_PRIVATE|))
+ Creates a private copy-on-write mapping, so changes to the
+ contents of the mmap object will be private to this process
+
+ : ((|options|))
+ Hash. If one of the options ((|length|)) or ((|offset|))
+ is specified it will not possible to modify the size of
+ the mapped file.
+
+ : ((|length|))
+ Maps ((|length|)) bytes from the file
+
+ : ((|offset|))
+ The mapping begin at ((|offset|))
+
+ : ((|advice|))
+ The type of the access (see #madvise)
+
+
+--- unlockall
+ reenable paging
+
+== Methods
+
+--- extend(count)
+ add ((|count|)) bytes to the file (i.e. pre-extend the file)
+
+--- madvise(advice)
+ ((|advice|)) can have the value ((|Mmap::MADV_NORMAL|)),
+ ((|Mmap::MADV_RANDOM|)), ((|Mmap::MADV_SEQUENTIAL|)),
+ ((|Mmap::MADV_WILLNEED|)), ((|Mmap::MADV_DONTNEED|))
+
+--- mprotect(mode)
+ change the mode, value must be "r", "w" or "rw"
+
+--- mlock
+ disable paging
+
+--- msync
+--- flush
+ flush the file
+
+--- munlock
+ reenable paging
+
+--- munmap
+ terminate the association
+
+=== Other methods with the same syntax than for the class String
+
+
+--- self == other
+ comparison
+
+--- self > other
+ comparison
+
+--- self >= other
+ comparison
+
+--- self < other
+ comparison
+
+--- self <= other
+ comparison
+
+--- self === other
+ used for ((|case|)) comparison
+
+--- self << other
+ append ((|other|)) to ((|self|))
+
+--- self =~ other
+ return an index of the match
+
+--- self[nth]
+ retrieve the ((|nth|)) character
+
+--- self[start..last]
+ return a substring from ((|start|)) to ((|last|))
+
+--- self[start, length]
+ return a substring of ((|lenght|)) characters from ((|start|))
+
+--- self[nth] = val
+ change the ((|nth|)) character with ((|val|))
+
+--- self[start..last] = val
+ change substring from ((|start|)) to ((|last|)) with ((|val|))
+
+--- self[start, len] = val
+ replace ((|length|)) characters from ((|start|)) with ((|val|)).
+
+--- self <=> other
+ comparison : return -1, 0, 1
+
+--- casecmp(other) >= 1.7.1
+
+--- concat(other)
+ append the contents of ((|other|))
+
+--- capitalize!
+ change the first character to uppercase letter
+
+--- chop!
+ chop off the last character
+
+--- chomp!([rs])
+ chop off the line ending character, specified by ((|rs|))
+
+--- count(o1 [, o2, ...])
+ each parameter defines a set of character to count
+
+--- crypt(salt)
+ crypt with ((|salt|))
+
+--- delete!(str)
+ delete every characters included in ((|str|))
+
+--- downcase!
+ change all uppercase character to lowercase character
+
+--- each_byte {|char|...}
+ iterate on each byte
