These functions are used for implementing barriers.
void __kmpc_barrier | ( | ident_t * | loc, |
kmp_int32 | global_tid | ||
) |
loc | source location information |
global_tid | thread id. |
Execute a barrier.
Definition at line 680 of file kmp_csupport.cpp.
kmp_int32 __kmpc_barrier_master | ( | ident_t * | loc, |
kmp_int32 | global_tid | ||
) |
loc | source location information |
global_tid | thread id. |
Start execution of a combined barrier and master. The barrier is executed inside this function.

kmp_int32 __kmpc_barrier_master_nowait | ( | ident_t * | loc, |
kmp_int32 | global_tid | ||
) |
loc | source location information |
global_tid | thread id. |
Start execution of a combined barrier and master(nowait) construct. The barrier is executed inside this function. There is no equivalent "end" function, since the
Definition at line 1629 of file kmp_csupport.cpp.
void __kmpc_end_barrier_master | ( | ident_t * | loc, |
kmp_int32 | global_tid | ||
) |
loc | source location information |
global_tid | thread id. |
Complete the execution of a combined barrier and master. This function should only be called at the completion of the master
code. Other threads will still be waiting at the barrier and this call releases them.

void __kmpc_end_reduce | ( | ident_t * | loc, |
kmp_int32 | global_tid, | ||
kmp_critical_name * | lck | ||
) |
loc | source location information |
global_tid | global thread id. |
lck | pointer to the unique lock data structure |
Finish the execution of a blocking reduce. The lck
pointer must be the same as that used in the corresponding start function.

loc | source location information |
global_tid | global thread id. |
lck | pointer to the unique lock data structure |
Finish the execution of a reduce nowait.

void __kmpc_flush | ( | ident_t * | loc | ) |
loc | source location information. |
Execute flush
. This is implemented as a full memory fence. (Though depending on the memory ordering convention obeyed by the compiler even that may not be necessary).
