Hi all,
I have some problems with the Channel Access library use,
more precisely the use of /*ca_array_put_callback*/ with STRINGS !
We are using a peace of exemple C code, picked-up at :
*http://lansce.lanl.gov/EPICSdata/ca/client*, that uses this CA API.

We have some problems with the ca_array_put_callback when we want to
write strings.
We use this code to put a string in the DESC field of a record,

The problem is that only the first caracter of the string is written to
the PV,

The callback is called, everything seem to bee correct except that there
is only the first caracter in the destination.
The /*ca_array_put_callback*/ works fine with other type of data
The /*ca_array_put*/ works fine with all type of data
we use the 3.14.9 release.
Thanx for your help.
