2066 | # to process. This name is the name of a global array holding the | |
2067 | # variable's properties (object name, type, etc). | |
2068 | # | |

2073 | # | |

2078 | # members: | |
2079 | # | |
2080 | # obj_name - the object name for accessing this variable via MI | |
2081 | # display_name - the display name for this variable (exp="display_name" in | |
2082 | # the output of -var-list-children) | |
2083 | # type - the type of this variable (type="type" in the output | |
2084 | # of -var-list-children, or the special tag "anonymous" | |
2085 | # path_expr - the "-var-info-path-expression" for this variable | |
440e2fca KS |
2086 | # NOTE: This member cannot be used reliably with typedefs. |
2087 | # Use with caution! | |

2089 | # parent - the variable name of the parent varobj |
2090 | # children - a list of children variable names (which are the | |
