If 23 the argument has any other value, the argument is returned unchanged. If the 24 argument of \fBtolower()\fR represents an upper-case letter, and there exists a 25 corresponding lower-case letter (as defined by character type information in 26 the program locale category \fB\fR\fBLC_CTYPE\fR\fB), \fR the result is the 27 corresponding lower-case letter. All other arguments in the domain are returned 28 unchanged. 29 .sp 30 .LP 31 The function \fBtolower_l()\fR behaves identically to \fBtolower()\fR, except 32 instead of operating in the current environemtn, it operates in the environment 33 specified by \fIloc\fR. 34 .SH RETURN VALUES 35 .sp 36 .LP 37 On successful completion, \fBtolower()\fR returns the lower-case letter 38 corresponding to the argument passed. Otherwise, it returns the argument 39 unchanged. 40 .SH ERRORS 41 .sp 42 .LP 43 No errors are defined. 44 .SH ATTRIBUTES 45 .sp 46 .LP 47 See \fBattributes\fR(5) for descriptions of the following attributes: 48 .sp 49 50 .sp 51 .TS 52 box; 53 c | c 54 l | l . 55 ATTRIBUTE TYPE ATTRIBUTE VALUE 56 _ 57 CSI Enabled 58 _ 59 Interface Stability Standard 60 _ 61 MT-Level MT-Safe 62 .TE 63 64 .SH SEE ALSO 65 .sp 66 .LP 67 \fB_tolower\fR(3C), \fBsetlocale\fR(3C), \fBattributes\fR(5), 68 \fBstandards\fR(5)
