PA_ReadWrite (tableNum)
| Parameter | Type | Description | |
| tableNum | short | → | Table number |
Description
The routine
PA_ReadWrite
works like the 4th Dimension
READ WRITE
command: it changes the state of table number
tableNum
to read/write for the process where it is called.
Unlike the 4D command, you cannot change the state of all the tables in one call (this can be done when using the syntax
READ WRITE(*)
).
A plug-in should not change the read-write status of a table;, the 4th Dimension developer would not approve. However, if running in its own external process, it should set the access mode of all the tables to read-only.
Example
Setting all tables to read write.
for(i = 1; i <= PA_CountTables(); i++)
PA_ReadWrite(i);

Error Handling
Use
PA_GetLastError
to see if an error occurred (bad table number).
