21 26 .SH DESCRIPTION
22 -.sp
23 27 .LP
24 28 The \fBstrxfrm()\fR function transforms the string pointed to by \fIs2\fR and
25 29 places the resulting string into the array pointed to by \fIs1\fR. The
26 30 transformation is such that if \fBstrcmp\fR(3C) is applied to two transformed
27 31 strings, it returns a value greater than, equal to or less than \fB0\fR,
28 32 corresponding to the result of \fBstrcoll\fR(3C) applied to the same two
29 33 original strings. No more than \fIn\fR bytes are placed into the resulting
30 34 array pointed to by \fIs1\fR, including the terminating null byte. If \fIn\fR
31 35 is \fB0\fR, \fIs1\fR is permitted to be a null pointer. If copying takes place
32 36 between objects that overlap, the behavior is undefined.
33 -.sp
34 37 .LP
35 38 The \fBstrxfrm()\fR function does not change the setting of \fBerrno\fR if
36 39 successful.
37 -.sp
38 40 .LP
39 41 Since no return value is reserved to indicate an error, an application wishing
40 42 to check for error situations should set \fBerrno\fR to 0, then call
41 43 \fBstrxfrm()\fR, then check \fBerrno\fR.
44 +.LP
45 +The \fBstrxfrm_l()\fR functions behaves identically to the function
46 +\fBstrxfrm()\fR, except instead of operating in the current locale it
47 +operates in the locale specified by the argument \fIloc\fR.
42 48 .SH RETURN VALUES
43 -.sp
44 49 .LP
45 50 Upon successful completion, \fBstrxfrm()\fR returns the length of the
46 51 transformed string (not including the terminating null byte). If the value
47 52 returned is \fIn\fR or more, the contents of the array pointed to by \fIs1\fR
48 53 are indeterminate.
49 -.sp
50 54 .LP
51 55 On error, \fBstrxfrm()\fR may set \fBerrno\fR but no return value is reserved
52 56 to indicate the error.
53 57 .SH USAGE
54 -.sp
55 58 .LP
56 59 The transformation function is such that two transformed strings can be ordered
57 60 by \fBstrcmp\fR(3C) as appropriate to collating sequence information in the
58 -program's locale (category \fBLC_COLLATE\fR).
59 -.sp
61 +locale (category \fBLC_COLLATE\fR).
60 62 .LP
61 63 The fact that when \fIn\fR is \fB0\fR, \fIs1\fR is permitted to be a null
62 64 pointer, is useful to determine the size of the \fIs1\fR array prior to making
63 65 the transformation.
64 66 .SH EXAMPLES
65 67 .LP
66 68 \fBExample 1 \fRA sample of using the \fBstrxfm()\fR function.
67 -.sp
68 69 .LP
69 70 The value of the following expression is the size of the array needed to hold
70 71 the transformation of the string pointed to by \fIs\fR.
