Defines the format for affirmative and negative system responses.
The LC_MESSAGES category of a locale definition source file defines the format for affirmative and negative system responses. This category begins with an LC_MESSAGES category header and terminates with an END LC_MESSAGES category trailer.
All operands for the LC_MESSAGES category are defined as strings or extended regular expressions enclosed by " " (double-quotation marks). These operands are separated from the keyword they define by one or more blanks. Two adjacent " " (double-quotation marks) indicate an undefined value. The following keywords are recognized in the LC_MESSAGES category:
| Item | Description |
|---|---|
| copy | Specifies the name of an existing locale to be used as the definition of this category. If a copy statement is included in the file, no other keyword can be specified. |
| yesexpr | Specifies an extended regular expression that describes the acceptable affirmative response to a question expecting an affirmative or negative response. |
| noexpr | Specifies an extended regular expression that describes the acceptable negative response to a question expecting an affirmative or negative response. |
| yesstr | A colon-separated string of acceptable affirmative responses. This string is accessible to applications through the nl_langinfo subroutine as nl_langinfo (YESSTR). |
| nostr | A colon-separated string of acceptable negative responses. This string is accessible to applications through the nl_langinfo subroutine as nl_langinfo (NOSTR). |
The following is an example of a possible LC_MESSAGES category listed in a locale definition source file:
LC_MESSAGES
#
yesexpr "([yY][[:alpha:]]*)|(OK)"
noexpr "[nN][[:alpha:]]*"
yesstr "Y:y:yes"
nostr "N:n:no"
#
