76 R"(
77
78 This auto-generated function is passed in three arguments:
79
80 frame: an lldb.SBFrame object for the frame which hit breakpoint.

82 bp_loc: an lldb.SBBreakpointLocation object that represents the breakpoint location that was hit.
83
84 dict: the python session dictionary hit.

93 The function itself must have either of the following prototypes:
94
95 def breakpoint_callback(frame, bp_loc, internal_dict):
96 # Your code goes here

107 \n\n\
108 Note that the global variable 'lldb.frame' will NOT be updated when \
109 this function is called, so be sure to use the 'frame' argument. The 'frame' argument \
110 can get you to the thread via frame.GetThread(), the thread can get you to the \
