Coding Conventions
ThreadX File
Names
261
All ThreadX C file names take the form
TX_c[x].C
where c represents the first initial letter of the
component and [x] represents a variable number of
supplemental initial letters used to identify the
function contained in the file. For example, file
tx_tc.c contains the function _tx_thread_create and
file tx_ike.c contains the function
_tx_initialize_kernel_enter.
Component specification file names are slightly
different, taking on the form
TX_ccc.H
where the ccc field represents the first three
characters of the component’s name. For example,
the file tx_tim.h contains the timer component
specification.
The file naming conventions make it easy to
distinguish ThreadX files from all other application
source files.
ThreadX Name
Space
In a similar vein, all ThreadX functions and global
data have a leading _tx in their name. This keeps
ThreadX global symbols separate from the
application symbols and in one contiguous area of
load map created by the linker.
i
Most development tools will insert an additional
underscore in front of all global symbols.
For ANSI compliance and greater compiler
compatibility, all symbolic names in ThreadX are
limited to 31 characters.
