.SH "NAME"
\fBXmConvertStringToUnits\fP \(em A function that converts a string specification to a unit value
.iX "XmConvertStringToUnits"
.SH "SYNOPSIS"
.PP
.nf
#include <Xm/Xm\&.h>
\fBint \fBXmConvertStringToUnits\fP\fR(
\fBScreen *\fBscreen\fR\fR,
\fBString \fBspec\fR\fR,

\fBXtEnum *\fBparse_error\fR\fR);
.fi
.SH "DESCRIPTION"
.PP
\fBXmConvertStringToUnits\fP converts a string specification value and
returns the converted value as the return value from the function\&.
This function uses the specified screen\&'s resolution to compute the
number of units for the string specification\&.
.IP "\fIscreen\fP" 10
Specifies the screen whose resolution is to be used for the computation\&.
.IP "\fIspec\fP" 10
Specifies the string, in \fI<floating value><unit>\fP format, to be
converted\&.
.IP "\fIorientation\fP" 10
Specifies whether the converter uses the horizontal or vertical screen
resolution when performing the conversion\&. The \fIorientation\fP
parameter can have values of \fBXmHORIZONTAL\fP or \fBXmVERTICAL\fP\&.
.IP "\fIto_type\fP" 10
Converts the value to the unit type specified\&.
Refer to the \fBXmNunitType\fP resource of the
\fBXmGadget\fP, \fBXmManager\fP, or \fBXmPrimitive\fP reference page\&.
This parameter can have one of
the following values:
.RS
.IP "\fBXmPIXELS\fP" 10
The returned value will be the number of pixels\&.
.IP "\fBXmMILLIMETERS\fP" 10
The returned value will be the number of millimeters\&.
.IP "\fBXm100TH_MILLIMETERS\fP" 10
The returned values will be the number of 1/100 millimeters\&.
.IP "\fBXmCENTIMETERS\fP" 10
The returned values will be the number of centimeters\&.
.IP "\fBXmINCHES\fP" 10
The returned values will be the number of inches\&.
.IP "\fBXm1000TH_INCHES\fP" 10
The returned values will be the number of 1/100 inches\&.
.IP "\fBXmPOINTS\fP" 10
The returned values will be the number of points\&.
A point is a text processing unit
defined as 1/72 of an inch\&.
.IP "\fBXm100TH_POINTS\fP" 10
The returned values will be the number of 1/100 points\&.
.IP "\fBXmFONT_UNITS\fP" 10
All values provided to the widget are treated as font
units\&. A font unit has horizontal and vertical components\&.
These are the values of the XmScreen resources \fBXmNhorizontalFontUnit\fP
and \fBXmNverticalFontUnit\fP\&.
.IP "\fBXm100TH_FONT_UNITS\fP" 10
All values provided to the widget are
treated as 1/100 of a font unit\&.
A font unit has horizontal and vertical components\&.
These are the values of the XmScreen resources \fBXmNhorizontalFontUnit\fP
and \fBXmNverticalFontUnit\fP\&.
.RE
.IP "\fIparse_error\fP" 10
Specifies if a parsing error occurred\&. This is set to a value of True
indicates that an error occurred, a value of False to indicate no error\&.
.SH "RETURN"
.PP
Returns the converted value\&.
If a NULL screen, incorrect \fIorientation\fP,
or incorrect \fIunit_type\fP
is supplied as parameter data, or if a parsing error occurred, 0
(zero) is returned\&.
.SH "RELATED"
.PP
\fBXmConvertUnits\fP(3), \fBXmSetFontUnits\fP(3), and \fBXmScreen\fP(3)\&.
