Change the current process’s real and effective group ID to that specified by group. Returns the new group ID. Not available on all platforms.
[Process.gid, Process.egid] #=> [0, 0] Process::GID.change_privilege(33) #=> 33 [Process.gid, Process.egid] #=> [33, 33]
Set
the effective group ID, and if possible, the saved group ID of the process to the given group. Returns the new effective group ID. Not available on all platforms.
[Process.gid, Process.egid] #=> [0, 0] Process::GID.grant_privilege(31) #=> 33 [Process.gid, Process.egid] #=> [0, 33]
Returns true
if the real and effective group IDs of a process may be exchanged on the current platform.
Returns true
if the current platform has saved group ID functionality.
Get all [gem, version] from the command line.
An argument in the form gem:ver is pull apart into the gen name and version, respectively.
Finds a spec and the source_uri it came from for gem gem_name
and version
. Returns an Array of specs and sources required for installation of the gem.
accessor to Fiddle::CStructEntity
accessor to Fiddle::CUnionEntity
Calculates the offsets and sizes for the given types
in the struct.
Calculate the necessary offset and for each union member with the given types
Parses the configuration data read from io
, see also parse.
Raises a ConfigError
on invalid configuration data.
Send the given command
to this engine.
Raises an EngineError
if the command
fails.
Emit an arbitrary object obj
and tag
Called when a sequence is started.
anchor
is the anchor associated with the sequence or nil. tag
is the tag associated with the sequence or nil. implicit
a boolean indicating whether or not the sequence was implicitly started. style
is an integer indicating the list style.
See the constants in Psych::Nodes::Sequence
for the possible values of style
.
Here is a YAML document that exercises most of the possible ways this method can be called:
--- - !!seq [ a ] - &pewpew - b
The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:seq", false, 2 ] ["pewpew", nil, true, 1 ]
Called when a sequence ends.
Parse and return a Time
from string
common
This method is called when a parse error is found.
ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str
.
ERROR_VALUE is a value of error token.
value_stack is a stack of symbol values. DO NOT MODIFY this object.
This method raises ParseError
by default.
If this method returns, parsers enter “error recovering mode”.
Creates a new Socket::AncillaryData
object which contains file descriptors as data.
p Socket::AncillaryData.unix_rights(STDERR) #=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 2>
