Method Detail

getIntDefine

protected static int getIntDefine(java.lang.String definedName)

This function retreives a value that is defined in the operating system's headers. Because values like open()'s O_CREAT flag, errno values like EBADF and other values might be defined differently on different OS flavours, it is not sufficient to simply hard-code them in the OS wrapper class. Therefore, OS Wrapper classes use a lookup mechanism to initialize their static final variables. So for instance, the O_CREAT flag for Unix's open() is defined as static final int O_CREAT member variable, initialized to the return value of the getIntDefine("O_CREAT") function call. If a defined name is given that is not known to the native implementation, an IllegalArgumentException is thrown

Parameters:

definedName - name of the define to look up

Returns:

the integer value associated with the given definedName.
