DwtDrmRCBuffer(3Dwt)DwtDrmRCBuffer(3Dwt)Name
DwtDrmRCBuffer - Returns a pointer to the memory buffer.
Syntax
#include <X11/DwtAppl.h>
char * DwtDrmRCBuffer(context_id)
DRMResourceContextPtr context_id;
Arguments
context_id
Specifies the resource context to read.
Description
The DwtDrmRCBuffer macro returns a pointer to the memory buffer that contains the data for this resource context. No validity checking is
done on the resource context; the caller must ensure that the resource context pointer is valid.
Return Values
Pointer to the memory buffer.

DwtInitGetSegment(3Dwt)DwtInitGetSegment(3Dwt)Name
DwtInitGetSegment - Returns the initialized context of the compound-string.
Syntax
int DwtInitGetSegment(context, compound_string)
DwtCompStringContext *context;
DwtCompString compound_string;
Arguments
context Specifies a context to be filled by this function. You should have previously allocated this context.
compound_string
Specifies the compound-string.
Description
The DwtInitGetSegment function returns the initialized context associated with the compound-string you specified (compound_string). You
must use this returned context in a call to DwtGetNextSegment.
Note that the performance of DwtInitGetSegment (used in conjunction with DwtGetNextSegment to fetch multiple segments from a compound-
string) has degraded from Version 1.0 of the toolkit.
A new function, DwtStringInitContext, not only provides better performance, it also creates the context structure that you must allocate
separately when using DwtInitGetSegment. To improve performance, convert calls from DwtInitGetSegment to DwtStringInitContext, and use
DwtStringFreeContext to free the context structure when you are finished with it.
Return Values
This function returns one of these status return constants:
DwtSuccess Normal completion.
DwtEndCS The string specified in
compound_string is NULL.
DwtFail The string specified in
compound_string is not a
compound-string.

I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)

In other words is there kind of an equal Linux with Unix?
