As the sizeof(struct) may give different value between client and server programs, how do i align properly for boundary conditions.
You cannot unless the application is only used on platforms with exactly the same programming model i.e. LP64, IPL32, LP16, etc. You need to select a data interchange format and then encode or decode to that format.
Howdy,
Supposing I want to output the following code to the screen in a bash script, this works fine until you use variables as below, because the variable could be of any length, meaning the screen output for line 2 will have the ultimate # out of alignment.

ddi_model_convert_from
ddi_model_convert_from(9F) Kernel Functions for Drivers ddi_model_convert_from(9F)NAME
ddi_model_convert_from - determine data model type mismatch
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
uint_tddi_model_convert_from(uint_t model);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
model The data model type of the current thread.
DESCRIPTION
ddi_model_convert_from() is used to determine if the current thread uses a different C Language Type Model than the device driver. The
64-bit version of Solaris will require a 64-bit kernel to support both 64-bit and 32-bit user mode programs. The difference between a
32-bit program and a 64-bit program is in its C Language Type Model: a 32-bit program is ILP32 (integer, longs, and pointers are 32-bit)
and a 64-bit program is LP64 (longs and pointers are 64-bit). There are a number of driver entry points such as ioctl(9E) and mmap(9E)
where it is necessary to identify the C Language Type Model of the user-mode originator of an kernel event. For example any data which
flows between programs and the device driver or vice versa need to be identical in format. A 64-bit device driver may need to modify the
format of the data before sending it to a 32-bit application. ddi_model_convert_from() is used to determine if data that is passed between
the device driver and the application requires reformatting to any non-native data model.
RETURN VALUES
DDI_MODEL_ILP32 A conversion to/from ILP32 is necessary.
DDI_MODEL_NONE No conversion is necessary. Current thread and driver use the same data model.
CONTEXT
ddi_model_convert_from() can be called from any context.
EXAMPLES
Example 1: : Using ddi_model_convert_from() in the ioctl() entry point to support both 32-bit and 64-bit applications.
The following is an example how to use ddi_model_convert_from() in the ioctl() entry point to support both 32-bit and 64-bit applications.
struct passargs32 {
int len;
caddr32_t addr;
};
struct passargs {
int len;
caddr_t addr;
};
xxioctl(dev_t dev, int cmd, intptr_t arg, int mode,
cred_t *credp, int *rvalp) {
struct passargs pa;
switch (ddi_model_convert_from(mode & FMODELS)) {
case DDI_MODEL_ILP32:
{
struct passargs32 pa32;
ddi_copyin(arg, &pa32, sizeof (struct passargs32), mode);
pa.len = pa32.len;
pa.address = pa32.address;
break;
}
case DDI_MODEL_NONE:
ddi_copyin(arg, &pa, sizeof (struct passargs), mode);
break;
}
do_ioctl(&pa);
....
}
