Detailed Description

These functions are used for implementing #pragma omp for, #pragma omp sections, #pragma omp single and #pragma omp master constructs.

When handling loops, there are different functions for each of the signed and unsigned 32 and 64 bit integer types which have the name suffixes _4, _4u, _8 and _8u. The semantics of each of the functions is the same, so they are only described once.

Static loop scheduling is handled by __kmpc_for_static_init_4 and friends. Only a single call is needed, since the iterations to be executed by any give thread can be determined as soon as the loop parameters are known.

Dynamic scheduling is handled by the __kmpc_dispatch_init_4 and __kmpc_dispatch_next_4 functions. The init function is called once in each thread outside the loop, while the next function is called each time that the previous chunk of work has been exhausted.

kmp_int32  global_tid,
kmp_critical_name *  crit 
)
Parameters
locsource location information.
global_tidglobal thread number .
critidentity of the critical section. This could be a pointer to a lock associated with the critical section, or some other suitably unique value.

Enter code protected by a critical construct. This function blocks until the executing thread can enter the critical section.

kmp_int32  global_tid 
)
Parameters
locsource location information
global_tidglobal thread number
Returns
One if this thread should execute the single construct, zero otherwise.

Test whether to execute a single construct. There are no implicit barriers in the two "single" calls, rather the compiler should introduce an explicit barrier if it is required.

kmp_int32 *  p_last,

kmp_int32 *  p_ub,

)
Parameters
locSource location
gtidGlobal thread id
p_lastpointer to last iteration flag
p_lbpointer to Lower bound
p_ubpointer to Upper bound
p_stStep (or increment if you prefer)
incrLoop increment
chunkThe chunk size to block with

The functions compute the upper and lower bounds and stride to be used for the set of iterations to be executed by the current team from the statically scheduled loop that is described by the initial values of the bounds, stride, increment and chunk for the distribute construct as part of composite distribute parallel loop construct. These functions are all identical apart from the types of the arguments.
