fea681da | 37 | .SH DESCRIPTION |
63aa9df0 | 38 | .BR catgets () |
fea681da MK |
39 | reads the message |
40 | .IR message_number , | |
41 | in set | |
42 | .IR set_number , | |
43 | from the message catalog identified by | |
44 | .IR catalog , | |
45 | where | |
46 | .I catalog | |
47 | is a catalog descriptor returned from an earlier call to | |
48 | .BR catopen (3). | |
e357a0a4 MK |
49 | The fourth argument, |
50 | .IR message , | |
fea681da | 51 | points to a default message string which will be returned by |
63aa9df0 | 52 | .BR catgets () |
c13182ef MK |
53 | if the identified message catalog is not currently available. |
54 | The | |
fea681da | 55 | message-text is contained in an internal buffer area and should be copied by |
c13182ef MK |
56 | the application if it is to be saved or modified. |
57 | The return string is | |
1aff5804 | 58 | always terminated with a null byte (\(aq\\0\(aq). |

60 | .LP |
61 | On success, | |
63aa9df0 | 62 | .BR catgets () |
fea681da MK |
63 | returns a pointer to an internal buffer area |
64 | containing the null-terminated message string. | |
65 | On failure, | |
63aa9df0 | 66 | .BR catgets () |
fea681da MK |
67 | returns the value |
68 | .IR message . | |

fea681da | 76 | .SH NOTES |
f4dc1f56 MK |
77 | The |
78 | .BR catgets () | |
79 | function is available only in libc.so.4.4.4c and above. | |
fea681da MK |
80 | The Jan 1987 X/Open Portability Guide specifies a more subtle |
81 | error return: | |
82 | .I message | |
83 | is returned if the message catalog specified by | |
84 | .I catalog | |
85 | is not available, while an empty string is returned | |
86 | when the message catalog is available but does not contain | |
87 | the specified message. | |
68e1685c | 88 | These two possible error returns seem to be discarded in SUSv2 |
d9bfdb9c | 89 | in favor of always returning |
fea681da | 90 | .IR message . |
