DwtGetNextSegment(3Dwt)DwtGetNextSegment(3Dwt)Name
DwtGetNextSegment - Gets information about the next segment in the compound-string.
Syntax
int DwtGetNextSegment(context, text_return,
charset_return, direction_r_to_l_return,
lang_return, rend_return)
DwtCompStringContext *context;
char *text_return;
long *charset_return;
int *direction_r_to_l_return;
long *lang_return;
long *rend_return;
Arguments
context Specifies the context for the call to DwtInitGetSegment. You initialize the context by calling DwtInitGetSegment, and it gets
incremented each time you call DwtGetNextSegment.
text_return
Returns the text in the next segment.
charset_return
Returns the character set in the next segment. Values for this argument can be found in the required file
/usr/include/cda_def.h.
direction_r_to_l_return
Returns the character direction value.
lang_return
For future use.
rend_return
For future use.
Description
The DwtGetNextSegment function obtains information about the next segment of the compound-string as determined by the context. The space
for the resulting compound-string is allocated with this function. After using this function, you should free this space by calling
XtFree.
Return Values
This function returns one of these status return constants:
DwtEndCS The context is at the end
of the compound-string.
DwtFail The context is not valid.
DwtSuccess Normal completion.

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.).
