(function)
yields the current time slice
(function)
(C11)
terminates the calling thread
(function)
detaches a thread
(function)
(C11)
blocks until a thread terminates
(function)
indicates a thread error status
(constant)
thrd_start_t
(C11)
a typedef of the function pointer type int(*)(void*), us' ;&,"vIE' ;&,"pan class="mw-geshi c source-c">thrd_create
(typedef)

[edit] Mutual exclusion

Defined in header <threads.h>
mtx_t mutex identifier
(C11)
creates a mutex
(function)
(C11)
blocks until locks a mutex
(function)
blocks until locks a mutex or times out
(function)
locks a mutex or returns without blocking if already locked
(function)
unlocks a mutex
(function)
destroys a mutex
(function)
defines the type of a mutex
(enum)
Call once
(C11)
calls a function exactly once
(function)

[edit] Condition variables

Defined in header <threads.h>
cnd_t condition variable identifier
(C11)
creates a condition variable
(function)
unblocks one thread blocked on a condition variable
(function)
unblocks all threads blocked on a condition variable
(function)
(C11)
blocks on a condition variable
(function)
blocks on a condition variable, with a timeout
(function)
destroys a condition variable
(function)

[edit] Thread-local storage

Defined in header <threads.h>
thread local type macro
(macro constant)
tss_t thread-specific storage pointer
maximum number of times destructors are called
(macro constant)
tss_dtor_t function pointer type void(*)(void*), used for TSS destructor
creates thread-specific storage pointer with a given destructor
(function)
(C11)
reads from thread-specific storage
(function)
(C11)
write to thread-specific storage
(function)
releases the resources held by a given thread-specific pointer
(function)

[edit] Reserved identifiers

Function names, type names, and enumeration constants that begin with either cnd_, mtx_, thrd_, or tss_, and a lowercase letter may be added to the declarations in the <threads.h> header in future revisions of the C standard, and portable programs should not use those identifiers.
