get_iter_at_line_offset

Description:

public void get_iter_at_line_offset (out TextIter iter, int line_number, int char_offset)

Obtains an iterator pointing to char_offset within the given line.

Note characters, not bytes; UTF-8 may encode one character as multiple bytes.

Before the 3.20 version, it was not allowed to pass an invalid location.

Since the 3.20 version, if line_number is greater than the number of lines in the this, the end iterator is returned. And if char_offset is off the end of the line, the iterator at the end of the line is returned.

Parameters:

this	a TextBuffer
iter	iterator to initialize
line_number	line number counting from 0
char_offset	char offset from start of line
