Pragma Details

This section describes each Compiler-available pragma. The pragmas are listed in alphabetical order and are divided into separate tables. The following table lists and defines the topics that appear in the description of each pragma.

Table 1. Pragma documentation topics

The following table is a description of the different scopes for pragmas.

Table 2. Definition of items that can appear in a pragma's scope topic
Scope	Description
File	The pragma is valid from the current position until the end of the source file. For example, if the pragma is in a header file included from a source file, the pragma is not valid in the source file.
Compilation Unit	The pragma is valid from the current position until the end of the whole compilation unit. For example, if the pragma is in a header file included from a source file, it is valid in the source file too.
Data Definition	The pragma affects only the next data definition. Ensure that you always use a data definition behind this pragma in a header file. If not, the pragma is used for the first data segment in the next header file or in the main file.
Function Definition	The pragma affects only the next function definition. Ensure that you use this pragma in a header file: The pragma is valid for the first function in each source file where such a header file is included if there is no function definition in the header file.
Next pragma with same name	The pragma is used until the same pragma appears again. If no such pragma follows this one, it is valid until the end of the file.
