+.SH NAME
+XtAllocateGC \- obtain a sharable GC with modifiable fields
+.SH SYNTAX
+.HP
+GC XtAllocateGC(Widget \fIw\fP, Cardinal \fIdepth\fP, XtGCMask
+\fIvalue_mask\fP, XGCValues *\fIvalues\fP, XtGCMask \fIdynamic_mask\fP,
+XtGCMask \fIunused_mask\fP);
+.SH ARGUMENTS
+.IP \fIvalues\fP 1i
+Specifies the actual values for this GC.
+.ds Vm fields of the values are specified
+.IP \fIvalue_mask\fP 1i
+Specifies which \*(Vm.
+.IP \fIw\fP 1i
+Specifies the widget.
+.IP \fIdepth\fP 1i
+Specifies the depth for which the returned GC is valid, or 0.
+.IP \fIdynamic_mask\fP 1i
+Specifies the fields of the GC that will be modified by the caller.
+.IP \fIunused_mask\fP 1i
+Specifies the fields of the GC that will not be needed by the caller.
+.SH DESCRIPTION
+The
+.ZN XtAllocateGC
+function returns a sharable GC that may be modified by the client.
+The \fIscreen\fP field of the specified widget or of the nearest
+widget ancestor of the specified object and the specified \fIdepth\fP
+argument supply the root and drawable depths for which the GC is to
+be valid. If \fIdepth\fP is zero the depth is taken from the \fIdepth\fP
+field of the specified widget or of the nearest widget ancestor of the
+specified object.
+.LP
+The \fIvalue_mask\fP argument specifies the fields of the GC that will
+be initialized with the respective members of the \fIvalues\fP structure.
+The \fIdynamic_mask\fP argument specifies fields that the caller intends
+to modify during program execution. The caller must ensure that the
+corresponding GC field is set prior to each use of the GC. The
+\fIunused_mask\fP argument specifies fields of the GC that are of no
+interest to the caller. The caller may make no assumptions about the
+contents of any fields specified in \fIunused_mask\fP. The caller may
+assume that at all times all fields not specified in either
+\fIdynamic_mask\fP or \fIunused_mask\fP have their default value if
+not specified in \fIvalue_mask\fP or the value specified by \fIvalues\fP.
+If a field is specified in both \fIvalue_mask\fP and \fPdynamic_mask\fP,
+the effect is as if it were specified only in \fIdynamic_mask\fP and
+then immediately set to the value in \fIvalues\fP. If a field is set
+in \fIunused_mask\fP and also in either \fIvalue_mask\fP or
+\fIdynamic_mask\fP, the specification in \fIunused_mask\fP is ignored.
+.LP
+.ZN XtAllocateGC
+tries to minimize the number of unique GCs created by comparing the
+arguments with those of previous calls and returning an existing GC
+when there are no conflicts.
+.ZN XtAllocateGC
+may modify and return an existing GC if it was allocated with a nonzero
+\fIunused_mask\fP.
