No. You cannot cast an array to a pointer type. Because there are subtle differences between them, they are not always interchangeable in SCL like they are in C.
Instead of using the following:
INT vr_get_foo(INT entry, INT index, file_table_t * out_buffer)
typedef struct
{
register ringer_types_t ringer_type;
BYTE alias_filename[(MAX_RINGER_ALIAS_NAME_LEN+1) *2];
UINT16 pad;
}ringer_file_table_t;
#pragma scl_function(v_get_mmedia_ringer)
#pragma scl_ptr(vr_get_mmedia_ringer, out_buffer, "OUT", PRIVATE)
Use this SCL instead:
#pragma scl_function(vr_get_mmedia_ringer)
#pragma scl_ptr(vr_get_get_mmedia_ringer, out_buffer, "OUT", PRIVATE)
#pragma scl_string(ringer_file_table_t, alias_filename, (MAX_RINGER_ALIAS_NAME_LEN+1) * 2)
