/* The ptid struct is a collection of the various "ids" necessary
|
|
for identifying the inferior. This consists of the process id
|
|
(pid), thread id (tid), and other fields necessary for uniquely
|
|
identifying the inferior process/thread being debugged. When
|
|
manipulating ptids, the constructors, accessors, and predicates
|
|
declared in this file should be used. These are as follows:
|
|
|
|
ptid_build - Make a new ptid from a pid, lwp, and tid.
|
|
pid_to_ptid - Make a new ptid from just a pid.
|
|
ptid_get_pid - Fetch the pid component of a ptid.
|
|
ptid_get_lwp - Fetch the lwp component of a ptid.
|
|
ptid_get_tid - Fetch the tid component of a ptid.
|
|
ptid_equal - Test to see if two ptids are equal.
|
|
ptid_is_pid - Test if a ptid is of the form (pid, 0, 0).
|
|
ptid_lwp_p - Test if a ptid's lwp component is non-zero.
|
|
ptid_tid_p - Test if a ptid's tid component is non-zero.
|
|
|
|
Please do NOT access the struct ptid members directly (except, of
|
|
course, in the implementation of the above ptid manipulation
|
|
functions). */
