Member Function Documentation

factory()

KLibFactory * KLibrary::factory

fileName()

TQString KLibrary::fileName

(

)

hasSymbol()

bool KLibrary::hasSymbol

(

const char *

name

)

const

Looks up a symbol from the library.

This is a very low level function that you usually don't want to use. Unlike symbol(), this method doesn't warn if the symbol doesn't exist, so if the symbol might or might not exist, better use hasSymbol() before symbol().

Parameters

name	the name of the symbol to check

Returns

true if the symbol exists

Since

3.1

name()

TQString KLibrary::name

(

)

const

Returns the name of the library.

Returns

The name of the library like "libkspread".

Definition at line 138 of file klibloader.cpp.

symbol()

void * KLibrary::symbol

(

const char *

name

)

const

Looks up a symbol from the library.

This is a very low level function that you usually don't want to use. Usually you should check using hasSymbol() whether the symbol actually exists, otherwise a warning will be printed.

Parameters

name	the name of the symbol to look up

Returns

the address of the symbol, or 0 if it does not exist

hasSymbol

Definition at line 181 of file klibloader.cpp.

unload()

void KLibrary::unload

This typically results in the deletion of this object. You should not reference its pointer after calling this function.
