.TH "XmDirectionMatch" "library call"
.SH "NAME"
\fBXmDirectionMatch\fP \(em A function that checks for a specified direction component
.iX "XmDirectionMatch"
.SH "SYNOPSIS"
.PP
.nf
#include <Xm/Xm\&.h>
Boolean XmDirectionMatch (\fId1, d2\fP)
        XmDirection     \fId1\fP;
        XmDirection     \fId2\fP;
\fB\fR(\fBvoid\fR)
.fi
.SH "DESCRIPTION"
.PP
\fBXmDirectionMatch\fP compares two \fBXmDirection\fR values\&.
The function returns a Boolean value depending on whether or
not the two input values "match\&."
The simplest match is when \fId1\fP and \fId2\fP are identical\&.
However, other matches are possible\&.
\fBXmDirectionMatch\fP attempts to compare specified bits only;
nonspecified bits automatically match\&.
.PP
For example, suppose that \fId1\fP equals
\fBXmTOP_TO_BOTTOM_RIGHT_TO_LEFT\fP\&. In this case, the function will
return True if \fId2\fP equals either \fBXmRIGHT_TO_LEFT\fP or
\fBXmTOP_TO_BOTTOM\fP\&. However, the function will return False if
\fId2\fP equals \fBXmTOP_TO_BOTTOM_LEFT_TO_RIGHT\fP,
\fBXmBOTTOM_TO_TOP_RIGHT_TO_LEFT\fP, or
\fBXmBOTTOM_TO_TOP_LEFT_TO_RIGHT\fP\&.
.PP
Note that direction can be thought of as having three components, a
horizontal component, a vertical component, and the precedence among
them\&. This means that in addition to the previously mentioned
directions, the function will still return False if \fId1\fP equals
\fBXmTOP_TO_BOTTOM_RIGHT_TO_LEFT\fP and \fId2\fP equals
\fBXmRIGHT_TO_LEFT_TOP_TO_BOTTOM\fP\&.
.IP "\fId1\fP" 10
Specifies an \fBXmDirection\fR value\&.
.IP "\fId2\fP" 10
Specifies an \fBXmDirection\fR value\&.
.SH "RETURN VALUES"
.PP
Returns True if \fId1\fP "matches" \fId2\fP; otherwise, returns False\&.
