If 26 the argument has any other value, the argument is returned unchanged. If the 27 argument of \fBtolower()\fR represents an upper-case letter, and there exists a 28 corresponding lower-case letter (as defined by character type information in 29 the locale category \fB\fR\fBLC_CTYPE\fR\fB), \fR the result is the 30 corresponding lower-case letter. All other arguments in the domain are returned 31 unchanged. 32 .LP 33 The function \fBtolower_l()\fR behaves identically to \fBtolower()\fR, except 34 instead of operating in the current locale, it operates in the locale 35 specified by \fIloc\fR. 36 .SH RETURN VALUES 37 .LP 38 On successful completion, \fBtolower()\fR returns the lower-case letter 39 corresponding to the argument passed. Otherwise, it returns the argument 40 unchanged. 41 .SH ERRORS 42 .LP 43 No errors are defined. 44 .SH ATTRIBUTES 45 .LP 46 See \fBattributes\fR(5) for descriptions of the following attributes: 47 .TS 48 box; 49 c | c 50 l | l . 51 ATTRIBUTE TYPE ATTRIBUTE VALUE 52 _ 53 CSI Enabled 54 _ 55 Interface Stability Standard 56 _ 57 MT-Level MT-Safe 58 .TE 59 60 .SH SEE ALSO 61 .LP 62 \fB_tolower\fR(3C), \fBnewlocale\fR(3C), \fBsetlocale\fR(3C), 63 \fBuselocale\fR(3C), \fBattributes\fR(5), \fBstandards\fR(5)
