OTF2_ErrorCode | OTF2_GlobalDefReader_SetCallbacks (OTF2_GlobalDefReader *reader, const OTF2_GlobalDefReaderCallbacks *callbacks, void *userData) |
Sets the callback functions for the given reader object. Every time when OTF2 reads a record, a callback function is called and the records data is passed to this function. Therefore the programmer needs to set function pointers at the "callbacks" struct for the record type he wants to read. More... | |
OTF2_ErrorCode | OTF2_GlobalDefReader_ReadDefinitions (OTF2_GlobalDefReader *reader, uint64_t recordsToRead, uint64_t *recordsRead) |
Reads the given number of records from the global definition reader. More... | |

OTF2_ErrorCode OTF2_GlobalDefReader_SetCallbacks | ( | OTF2_GlobalDefReader * | reader, |
const OTF2_GlobalDefReaderCallbacks * | callbacks, | ||
void * | userData | ||
) |
Sets the callback functions for the given reader object. Every time when OTF2 reads a record, a callback function is called and the records data is passed to this function. Therefore the programmer needs to set function pointers at the "callbacks" struct for the record type he wants to read.
reader | This given reader object will be set up with new callback functions. |
callbacks | Struct which holds a function pointer for each record type. OTF2_GlobalDefReaderCallbacks_New. |
userData | Data passed as argument userData to the record callbacks. |
OTF2_ErrorCode OTF2_GlobalDefReader_ReadDefinitions | ( | OTF2_GlobalDefReader * | reader, |
uint64_t | recordsToRead, | ||
uint64_t * | recordsRead | ||
) |
Reads the given number of records from the global definition reader.
reader | The records of this reader will be read when the function is issued. | |
recordsToRead | This variable tells the reader how much records it has to read. | |
[out] | recordsRead | This is a pointer to variable where the amount of actually read records is returned. This may differ to the given recordsToRead if there are no more records left in the trace. In this case the programmer can easily check that the reader has finished his job by checking recordsRead < recordsToRead. |
