Re: [Imgcif-l] renaming a data block?

Dear Michael,

   Please note cbf_set_datablockname, below.  Note that you have to
be in the datablock you intend to change.  The first thing the code
does is to look for a parent of type CBF_DATABLOCK.  It can 
fail if the target name is already in use.  In that case you need to copy 
instead of rename.  The necessary copy loop is in the code of cif2cbf.

   I did not get your sf mail (my spam filter is very tight).  Just
email me your sf username and I'll add you to the CBFlib project.

   I'll be a bit out of touch for a few days -- I am off to Dubuque
for a meeting.

   Regards,
     Herbert

   At the API level:

2.3.13 cbf_set_datablockname, cbf_set_saveframename

PROTOTYPE

#include "cbf.h"

int cbf_set_datablockname (cbf_handle handle, const char *datablockname);
int cbf_set_saveframename (cbf_handle handle. const char *saveframename);

DESCRIPTION

cbf_set_datablockname changes the name of the current data block to 
datablockname. cbf_set_saveframename changes the name of the current save 
frame to saveframename.

If a data block or save frame with this name already exists (comparison is 
case-insensitive), the function returns CBF_IDENTICAL.

ARGUMENTS
   handle	  CBF handle.
   datablockname	  The new data block name.
   datablockname	  The new save frame name.

RETURN VALUE

Returns an error code on failure or 0 for success.
