Definition at line 269 of file thread.h.

void Mutex::leaveMutex ( void  )
inherited

Leaving a mutex frees that mutex for use by another thread.

If the mutex has been entered (invoked) multiple times (recursivily) by the same thread, then it will need to be exited the same number of instances before it is free for re-use. This operation can also be done using the LEAVE_CRITICAL macro or by the – operator on a mutex.

enterMutex
void Keydata::load ( const char *  keypath)
inherited

Load additional key values into the currrent object from the specfied config source (a config file/section pair).

These values will overlay the current keywords when matches are found. This can be used typically in a derived config object class constructor to first load a /etc section, and then load a matching user specific entry from ~/. to override default system values with user specific keyword values.

Parameters
keypath(filepath/section)
void Keydata::load ( Define pairs)
inherited

Load default keywords into the current object.

This only loads keyword entries which have not already been defined to reduce memory usage. This form of Load is also commonly used in the constructor of a derived Keydata class.

Parameters
pairslist of NULL terminated default keyword/value pairs.
void ost::ScriptCommand::load ( Script::Define keywords)
protectedinherited

Load a set of keywords into the system keyword table.

This provides a convenient method of initializing and adding to the keyword indexes.

Parameters
keywordsdefined pair entries to load.
void Keydata::loadFile ( const char *  filepath,
const char *  keys = NULL,
const char *  pre = NULL 
)
inherited

Load additional keys into the current object using a real filename that is directly passed rather than a computed key path.

This also uses a [keys] section as passed to the object.

Parameters
filepathto load from
keyssection to parse from, or NULL to parse from head
preoptional key prefix
void Keydata::loadPrefix ( const char *  prefix,
const char *  keypath 
)
inherited

Load additional key values into the currrent object from the specfied config source (a config file/section pair).

These values will overlay the current keywords when matches are found. This can be used typically in a derived config object class constructor to first load a /etc section, and then load a matching user specific entry from ~/. to override default system values with user specific keyword values. This varient puts a prefix in front of the key name.

Parameters
prefix
keypath(filepath/section)
void Mutex::nameMutex ( const char *  name)
inlineinherited

Enable setting of mutex name for deadlock debug.

Parameters
namefor mutex.

Definition at line 248 of file thread.h.

Definition at line 240 of file thread.h.

void Keydata::setValue ( const char *  sym,
const char *  data 
)
inherited

Set (replace) the value of a given keyword.

This new value will become the value returned from getLast(), while the prior value will still be stored and found from getList().

Parameters
symkeyword name to set.
datastring to store for the keyword.
static unsigned ost::Script::storage ( Symbol sym)
staticinherited
static bool ost::Script::symindex ( Symbol sym,
short  offset 
)

bool Mutex::test ( void  )
inlineinherited

Future abi will use enter/leave/test members.

Returns
true if entered.

Definition at line 277 of file thread.h.

int ost::ScriptCommand::trap ( const char *  name,
bool  inherited = true 
)
protectedinherited

Add a trap handler symbolic identity to the keyword table.

These are used to handle signal mask coercion and event branch points in the compiler.

Parameters
nameof requested trap to add to the trap table.
inheritedstatus of trap.
Returns
assigned id number for the trap.
bool Mutex::tryEnterMutex ( void  )
inherited

Tries to lock the mutex for the current thread.

Behaves like enterMutex , except that it doesn't block the calling thread if the mutex is already locked by another thread.

Returns
true if locking the mutex was succesful otherwise false

enterMutex
leaveMutex
void Keydata::unlink ( void  )
inherited

Unlink the keydata object from the cache file stream.

This should be used if you plan to keepa Keydata object after it is loaded once all keydata objects have been loaded, otherwise the cfgFile stream will remain open. You can also use endKeydata().

staticinherited
static bool ost::ScriptCommand::useKeywords ( Line line,
const char *  list 
)
staticinherited

Test current command against a list of valid keywords.

Returns
