Further information

1. This funtion returns the source location (file name and line number) corresponding to a given line index. If the provided index is -1 and an execution context is available, the function returns information related to the statement being executed. If this value is -2, the location of the last statement is returned.

2. If parameter fname is NULL, the function returns in line the current line index ( i.e. the value of lndx or its updated value if it was given as a negative number).

3. If the returned line number is 0, the machine is currently executing a portion of the code for which there is no debugging information ( i.e. a package compiled without option -g or -G). In this case the fname information corresponds to the package name.
