Architecture-Independent Data Types

Instead of using native C/C++ scalar data types, function parameters, and return values in the TIBCO SmartSockets API, use SmartSockets data types that are independent of system architecture, as listed in Table 1. These data types make the SmartSockets API more portable and consistent across different 32-bit and 64-bit architectures.

Table 1 Summary of SmartSockets Data Types

T_INT1	one-byte integer	`signed char`	`signed char`
T_UINT1	unsigned one-byte integer	`unsigned char`	`unsigned char`
T_INT2	two-byte integer	`short`	`short`
T_UINT2	unsigned two-byte integer	`unsigned short`	`unsigned short`
T_INT4	four-byte integer	`long`	`int`
