add_struc_member

Add structure member.

This function can be used in two forms. First form: long add_struc_member(long id, string name, long offset, long flag, long typeid, long nbytes); Second form: long add_struc_member(long id, string name, long offset, long flag, long typeid, long nbytes, long target, long tdelta, long reftype);

arguments: id - structure type ID name - name of the new member offset - offset of the new member -1 means to add at the end of the structure flag - type of the new member. Should be one of FF_BYTE..FF_PACKREAL (see above) combined with FF_DATA typeid - if is_struct(flag) then typeid specifies the structure id for the member if is_off0(flag) then typeid specifies the offset base. if is_strlit(flag) then typeid specifies the string type (STRTYPE_...). if is_stroff(flag) then typeid specifies the structure id if is_enum(flag) then typeid specifies the enum id Otherwise typeid should be -1 nbytes - number of bytes in the new member the remaining arguments are allowed only if isOff0(flag) and you want to specify a complex offset expression target - target address of the offset expr. You may specify it as -1, ida will calculate it itself tdelta - offset target delta. usually 0 reftype - see REF_... definitions returns: 0 - ok, otherwise error code STRUC_ERROR_...
