Naming Conventions
About DSP/BIOS 1-11
Note:
Your program code should not call any built-in functions whose names
begin with MOD_F_. These functions are intended to be called only as
function parameters specified in the configuration.
Symbol names beginning with MOD_ and MOD_F_ (where MOD is any letter
code for a DSP/BIOS module) are reserved for internal use.
1.3.4 Data Type Names
The DSP/BIOS API does not explicitly use the fundamental types of C such
as int or char. Instead, to ensure portability to other processors that support
the DSP/BIOS API, DSP/BIOS defines its own standard data types. In most
cases, the standard DSP/BIOS types are uppercase versions of the
corresponding C types.
The data types, shown in Table 1-2, are defined in the std.h header file.
Table 1-2. DSP/BIOS Standard Data Types:
Additional data types are defined in std.h, but are not used by DSP/BIOS
APIs.
In addition, the standard constant NULL (0) is used by DSP/BIOS to signify
an empty pointer value. The constants TRUE (1) and FALSE (0) are used for
values of type Bool.
