put, preceding each by the file name, start position, and length. This information is used by (see insertmsg(1)). does not output strings
that are parameters of the routine (see catgets(3C)).
EXTERNAL INFLUENCES
Environment Variables
determines the interpretation of comments and string literals as single- and/or multi-byte characters.
determines the language in which messages are displayed.
If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization
variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
WARNINGS
outputs initialization strings of static string variables. Calling with these strings causes their replacement with a call to (see cat-
gets(3C)). Since the initializer must be a string, this assignment results in an invalid C declaration. For example, the following line:
