setcat(3C) SDK R4.11 setcat(3C)
NAME
setcat - define default catalog
SYNOPSIS
#include <pfmt.h>
char *setcat(const char *catalog);
DESCRIPTION
The routine setcat defines the default message catalog to be used by
subsequent calls to gettxt, pfmt, or lfmt that do not explicitly
specify a message catalog.
catalog must be limited to 14 characters. These characters must be
selected from a set of all characters values, excluding \0 (null) and
the ASCII codes for / (slash) and : (colon).
setcat 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, pfmt, or lfmt that do not
explicitly specify a catalog name will use
Message not found!!\n
as the default string.
Return Values
Upon success, setcat() returns a pointer to the catalog name. Upon
failure, setcat() returns a null pointer.
