| 2142 | ||||
| 2143 | __kmpc_copyprivate implements the interface for the private data broadcast | |||
| 2144 | needed for the copyprivate clause associated with a single region in an | |||
| 2145 | OpenMP<sup>*</sup> program (both C and Fortran). | |||
| 2146 | All threads participating in the parallel region call this routine. | |||
| 2147 | One of the threads (called the single thread) should have the <tt>didit</tt> | |||
| 2148 | variable set to 1 and all other threads should have that variable set to 0. | |||
| 2149 | All threads pass a pointer to a data buffer (cpy_data) that they have built. | |||
| 2150 | ||||
| 2151 | The OpenMP specification forbids the use of nowait on the single region when a | |||
| 2152 | copyprivate clause is present. However, @ref __kmpc_copyprivate implements a | |||
| 2153 | barrier internally to avoid race conditions, so the code generation for the | |||
| 2154 | single region should avoid generating a barrier after the call to @ref | |||
| 2155 | __kmpc_copyprivate. | |||
| 2156 | ||||
| 2157 | The <tt>gtid</tt> parameter is the global thread id for the current thread. | |||
| 2158 | The <tt>loc</tt> parameter is a pointer to source location information. | |||
| 2159 | ||||
| 2160 | Internal implementation: The single thread will first copy its descriptor | |||
| 2161 | address (cpy_data) to a team-private location, then the other threads will each | |||
| 2162 | call the function pointed to by the parameter cpy_func, which carries out the | |||
| 2163 | copy by copying the data using the cpy_data buffer. | |||
| 2164 | ||||
| 2165 | The cpy_func routine used for the copy and the contents of the data area defined | |||
| 2166 | by cpy_data and cpy_size may be built in any fashion that will allow the copy | |||
| 2167 | to be done. For instance, the cpy_data buffer can hold the actual data to be | |||
| 2168 | copied or it may hold a list of pointers to the data. The cpy_func routine must | |||
| 2169 | interpret the cpy_data buffer appropriately. | |||
| 2170 | ||||
| 2171 | The interface to cpy_func is as follows: | |||
| 2172 | @code | |||
| 2173 | void cpy_func( void *destination, void *source ) | |||
| 2174 | @endcode | |||
| 2175 | where void *destination is the cpy_data pointer for the thread being copied to | |||
| 2176 | and void *source is the cpy_data pointer for the thread being copied from. | |||
