Allocates and initializes an event table and sets the default event function
| Call | ||
| #include <vv_sys.h> | ||
| ETPTR et_def(size, default_fp) | ||
|
int size |
Number of entries to allow in table |
|
| EVENTFP default_fp | Pointer to default event function to install | |
| Returns | ||
| POINTER | A pointer to the initialized event table | |
| NULLP | Error. VV_ERR is set to the following: | |
| MEMLACK | There is insufficient memory to allocate the table | |
| Description
Memory is allocated for an event table of the desired number of entries plus one extra entry for an end-of-table marker. Since memory allocation is done with a call to mem_get(), which initializes each allocated byte to 0, all entries in the table are empty. If a default event function is specified, it is installed in the table. In the default event function entry, ET_DEFAULT is used as the event code. The end-of-table marker is installed in the last entry in the event table. |
