This function writes a FLOAT to a buffer at the specified offset.
Syntax |
set_float (buffer, i32 offset, float set_val) |
|---|---|
buffer |
Can be an array, structure, register |
offset |
Offset in bytes |
set_val |
FLOAT value to be written |
Validity |
Task, Rule |
Note |
NO range check is performed, it is up to the user to check that adding the offset and the data size does not exceed the maximum buffer size. See example. If the user wishes to write a float into the 'data' buffer of a structure of type bbc_msguser then he must use the function bcc_set_float(). The mirror function is the get_float() |
Once you have loaded the example program on a control, via a shell you can verify that set_float works. To do this, set a value between 0 and 127 - sizeof(my_data) to the variable offset, then set a non-zero value to the variable set_val and verify that the variable my_data is equal to set_val.
