setcat(3C) Standard C Library Functions setcat(3C)NAME
setcat - define default catalog
SYNOPSIS
#include <pfmt.h>
char *setcat(const char *catalog);
DESCRIPTION
The setcat() function defines the default message catalog to be used by subsequent calls to gettxt(3C), lfmt(3C), or pfmt(3C) that do not
explicitly specify a message catalog.
The catalog argument must be limited to 14 characters. These characters must be selected from a set of all characters values, excluding
(null) and the ASCII codes for / (slash) and : (colon).
The setcat() function assumes that the catalog exists. No checking is done on the argument.
A null pointer passed as an argument will result in the return of a pointer to the current default message catalog name. A pointer to an
empty string passed as an argument will cancel the default catalog.
If no default catalog is specified, or if catalog is an invalid catalog name, subsequent calls to gettxt(3C), lfmt(3C), or pfmt(3C) that do
not explicitely specify a catalog name will use Message not found!!
as default string.
RETURN VALUES
Upon successful completion, setcat() returns a pointer to the catalog name. Otherwise, it returns a null pointer.
EXAMPLES
Example 1 Example of setcat() function.
setcat("test");
gettxt(":10", "hello world
")

pfmt(3C) Standard C Library Functions pfmt(3C)NAME
pfmt - display error message in standard format
SYNOPSIS
#include <pfmt.h>
int pfmt(FILE *stream, long flags, char *format, ... /* arg */);
DESCRIPTION
The pfmt() retrieves a format string from a locale-specific message database (unless MM_NOGET is specified) and uses it for printf(3C)
style formatting of args. The output is displayed on stream.
The pfmt() function encapsulates the output in the standard error message format (unless MM_NOSTD is specified, in which case the output is
similar to printf()).
If the printf() format string is to be retrieved from a message database, the format argument must have the following structure:
<catalog>:<msgnum>:<defmsg>.
If MM_NOGET is specified, only the defmsg field must be specified.
The catalog field is used to indicate the message database that contains the localized version of the format string. This field must be
limited to 14 characters selected from the set of all characters values, excluding (null) and the ASCII codes for / (slash) and :
(colon).
The msgnum field is a positive number that indicates the index of the string into the message database.
If the catalog does not exist in the locale (specified by the last call to setlocale(3C) using the LC_ALL or LC_MESSAGES categories), or if
the message number is out of bound, pfmt() will attempt to retrieve the message from the C locale. If this second retrieval fails, pfmt()
uses the defmsg field of the format argument.
If catalog is omitted, pfmt() will attempt to retrieve the string from the default catalog specified by the last call to setcat(3C). In
this case, the format argument has the following structure:
:<msgnum>:<defmsg>.
The pfmt() will output Message not found!!
as format string if catalog is not a valid catalog name, if no catalog is specified (either
explicitely or with setcat()), if msgnum is not a valid number, or if no message could be retrieved from the message databases and defmsg
was omitted.
The flags argument determine the type of output (such as whether the format should be interpreted as is or encapsulated in the standard
message format), and the access to message catalogs to retrieve a localized version of format.
The flags argument is composed of several groups, and can take the following values (one from each group):
Output format control
MM_NOSTD Do not use the standard message format, interpret format as printf() format. Only catalog access control flags should be
specified if MM_NOSTD is used; all other flags will be ignored.
MM_STD Output using the standard message format (default value 0).
Catalog access control
MM_NOGET Do not retrieve a localized version of format. In this case, only the defmsg field of the format is specified.
MM_GET Retrieve a localized version of format from the catalog, using msgid as the index and defmsg as the default message
(default value 0).
Severity (standard message format only)
MM_HALT Generate a localized version of HALT, but do not halt the machine.
MM_ERROR Generate a localized version of ERROR (default value 0).
MM_WARNING Generate a localized version of WARNING.
MM_INFO Generate a localized version of INFO.
Additional severities can be defined. Add-on severities can be defined with number-string pairs with numeric values from the range [5-255],
using addsev(3C). The specified severity will be generated from the bitwise OR operation of the numeric value and other flags If the sever-
ity is not defined, pfmt() uses the string SEV=N, where N is replaced by the integer severity value passed in flags.
Multiple severities passed in flags will not be detected as an error. Any combination of severities will be summed and the numeric value
will cause the display of either a severity string (if defined) or the string SEV=N (if undefined).
Action
MM_ACTION Specify an action message. Any severity value is superseded and replaced by a localized version of TO FIX.
STANDARD ERROR MESSAGE FORMAT
The pfmt() function displays error messages in the following format:
label: severity: text
If no label was defined by a call to setlabel(3C), the message is displayed in the format:
severity: text
If pfmt() is called twice to display an error message and a helpful action or recovery message, the output can look like:
label: severity: textlabel: TO FIX: text
RETURN VALUES
Upon success, pfmt() returns the number of bytes transmitted. Upon failure, it returns a negative value:
-1 Write error to stream.
EXAMPLES
Example 1: Example of pfmt() function.
Example 1:
setlabel("UX:test");
pfmt(stderr, MM_ERROR, "test:2:Cannot open file: %s
", strerror(errno));
displays the message:
UX:test: ERROR: Cannot open file: No such file or directory
Example 2:
setlabel("UX:test");
setcat("test");
pfmt(stderr, MM_ERROR, ":10:Syntax error
");
pfmt(stderr, MM_ACTION, "55:Usage ...
");
displays the message
UX:test: ERROR: Syntax error
UX:test: TO FIX: Usage ...
USAGE
Since it uses gettxt(3C), pfmt() should not be used.
