====== command qsThreadInfo ======

**Format:** ‘qsThreadInfo’

**Meaning:** Obtain a list of all active thread IDs from the target (OS). Since there may be too many active threads to fit into one reply packet, this query works iteratively: it may require more than one query/reply sequence to obtain the entire list of threads. The first query of the sequence will be the ‘qfThreadInfo’ query; subsequent queries in the sequence will be the ‘qsThreadInfo’ query.

NOTE: This packet replaces the ‘qL’ query.

In response to each query, the target will reply with a list of one or more thread IDs, separated by commas. GDB will respond to each reply with a request for more thread ids (using the ‘qs’ form of the query), until the target responds with ‘l’ (lower-case ell, for last). Refer to thread-id syntax, for the format of the thread-id fields.

Note: GDB will send the qfThreadInfo query during the initial connection with the remote target, and the very first thread ID mentioned in the reply will be stopped by GDB in a subsequent message. Therefore, the stub should ensure that the first thread ID in the qfThreadInfo reply is suitable for being stopped by GDB. 

**Reply:** <code>m thread-id</code> A single thread ID 
<code>m thread-id,thread-id…</code> A comma-separated list of thread IDs 
<code>l</code> (lower case letter ‘L’) denotes end of list.
