Function dwarf_lineaddr() stores the program address corresponding to the source line specified in argument ln into the location pointed to by argument ret.
Function dwarf_linebeginstatement() sets the location pointed to by argument ret to 1 if the source line specified by the line descriptor ln is the beginning of a statement, or to 0 otherwise.
Function dwarf_lineblock() sets the location pointed to by argument ret to 1 if the source line specified by the line descriptor ln is the beginning of a basic block, or to 0 otherwise.
Function dwarf_lineendsequence() sets the location pointed to by argument ret to 1 if the program address associated with the line descriptor ln is the address immediately following the end of a sequence of target machine instructions, or to 0 otherwise.
Function dwarf_lineno() stores the line number of the source line associated with the line descriptor ln into the location pointed to by argument ret.
Function dwarf_lineoff() stores the column number within a line associated with descriptor ln into the location pointed to by argument ret. The retrieved column numbers are 1-based, with the value -1 indicating that column number information was not available.
Function dwarf_linesrc() stores a pointer to a NUL-terminated string containing the source file name associated with line descriptor ln into the location pointed to by argument ret. The full path of the source file is returned if possible. The memory used for the source file name string is managed by the DWARF(3) library and should not be directly freed by application code. Instead, portable code should use dwarf_dealloc(3) to indicate that the string should be freed.
Function dwarf_line_srcfileno() stores the index of the source file associated with the line descriptor ln in the location pointed to by argument ret. The returned value is 1-based index into the array of source file names returned by dwarf_srcfiles(3).
