!!DESCRIPTION |

|
| |
|
31 |
catopen() opens a message catalog and returns a catalog |
| |
|
32 |
descriptor. ''name'' specifies the name of the message |
| |
|
33 |
catalog to be opened. If ''name'' specifies and absolute |
| |
|
34 |
path, (i.e. contains a `__/__'__)__ then ''name'' |
| |
|
35 |
specifies a pathname for the message catalog. Otherwise, the |
| |
|
36 |
environment variable __NLSPATH__ is used |
| |
|
37 |
with ''name'' substituted for __%N__ (see |
| |
|
38 |
locale(7)). If __NLSPATH__ does not |
| |
|
39 |
exist in the environment, or if a message catalog cannot be |
| |
|
40 |
opened in any of the paths specified by |
| |
|
41 |
__NLSPATH__ , then the following paths are |
| |
|
42 |
searched in order |
| |
|
43 |
|
| |
|
44 |
|
| |
|
45 |
__/etc/locale/LC_MESSAGES |
| |
|
46 |
/usr/lib/locale/LC_MESSAGES |
| |
|
47 |
/usr/lib/locale/name/LC_MESSAGES__ |
| |
|
48 |
|
| |
|
49 |
|
| |
|
50 |
In all cases ''LC_MESSAGES'' stands for the current |
| |
|
51 |
setting of the __LC_MESSAGES__ category of |
| |
|
52 |
locale from a previous call to __setlocale__() and |
| |
|
53 |
defaults to the |
| |
|
54 |
__name'' refers to the catalog name. |
| |
|
55 |
|
| |
|
56 |
|
| |
|
57 |
The ''flag'' argument to catopen is used to indicate the |
| |
|
58 |
type of loading desired. This should be either |
| |
|
59 |
__MCLoadBySet__ or __MCLoadAll__. The former value |
| |
|
60 |
indicates that only the required set from the catalog is |
| |
|
61 |
loaded into memory when needed, whereas the latter causes |
| |
|
62 |
the initial call to __catopen__() to load the entire |
| |
|
63 |
catalog into memory. |
| |
|
64 |
|
| |
|
65 |
|
| |
|
66 |
__catclose()__ closes the message catalog identified by |
| |
|
67 |
''catalog''. It invalidates any subsequent references to |
| |
|
68 |
the message catalog defined by ''catalog''. |
| |
|
69 |
!!RETURN VALUE |
| |
|
70 |
|
| |
|
71 |
|
| |
|
72 |
__catopen()__ returns a message catalog descriptor of |
| |
|
73 |
type ''nl_catd'' on success. On failure, it returns |
| |
|
74 |
-1. |
| |
|
75 |
|
| |
|
76 |
|
| |
|
77 |
__catclose()__ returns 0 on success, or -1 on |
| |
|
78 |
failure. |
| |
|

These functions are only available in libc.so.4.4.4c and |
| |
|
83 |
above. In the case of linux, the catalog descriptor |
| |
|
84 |
''nl_catd'' is actually a mmap()'ed area of memory and |
| |
|
85 |
not a file descriptor, thus allowing catalogs to be |
| |
|
86 |
shared. |
