35 .Nd POSIX Threads Library
49 library provides an implementation of the standard
55 implementation is based on 1:1 thread model, therefore each
57 has a kernel thread, called a light-weight process (LWP).
59 Note that the system private thread interfaces upon which the
61 library is built are subject to change without notice.
62 In order to remain compatible with future
64 releases, programs must be linked against the dynamic version of the
66 Statically linked programs using the
68 threads framework may not work when run on a future version of the system.
70 .Bl -tag -width PTHREAD_DEBUGCOUNTERSXX
71 .It Ev PTHREAD_DIAGASSERT
72 Possible values are any combinations of:
74 .Bl -tag -width ignoreXX -offset indent -compact
76 Report errors to application by error return, but do not abort.
78 Abort on errors, creating a core dump for further debugging.
80 Do not log errors to stdout.
91 If not set in the environment, the
96 .It Ev PTHREAD_STACKSIZE
97 Integer value giving the stack size in kilobytes.
98 This allows to set a smaller stack size than the default stack size.
99 The default stack size is the current limit on the stack size as
100 set with the shell's command to change limits

162 should not be used in programs which link against the
164 library (whether threads are used or not).
