◆ allocate_arrays()

static void* allocate_arrays ( int  count,
float ***  floats,
char ***  chars,
const char *  name 
)
static

A utility function for allocating a number of arrays of the same length with easy error checking and de-allocation, and an easy way to add or remove arrays that are processed in this way when changing code.

floats, chars: NULL-terminated arrays of pointers to array pointers that need to be allocated.

Returns: pointer to the buffer that contains all of the arrays.

Update selected handle types to ensure valid state, e.g. deduce "Auto" types to concrete ones. Thereby sel_flag defines what qualifies as selected. Use when something has changed handle positions.

The caller needs to recalculate handles.

Parameters
sel_flagThe flag (bezt.f1/2/3) value to use to determine selection. Usually SELECT, but may want to use a different one at times (if caller does not operate on selection).
use_handleCheck selection state of individual handles, otherwise always update both handles if the key is selected.
