ZCOM C I/F Library Routines
LTFIND (3X)
NOTES The returned logical terminal table consists of the basic table and the
logical terminal table extension (the extension size is configurable in the
TTGEN configuration file). The size of this buffer should be large enough
to hold the information required from the LTT. An example of defining a
buffer of sufficient size would be:
struct {
zltt_type sys;
char ext[ZCOM_MAXLSIZE]; /* Max allowable extension */
ltt;
For example, to access the fields:
This allows <t to be used instead of ibuf in the ltfind call
.
EXAMPLE
#include <zcom/zcomsys.h>
#include <zcom/zcomcall.h>
int32 ierr;
zaddr_type zaddr;
char laddr[10];
int32 llen;
char ibuf[size]; /* where size is user-determined; must be >= len */
int32 len;
if (ierr = ltfind (&zaddr, laddr, llen, ibuf, len)) {
/* error return code */
}
else {
/* good return code */
}
ltt.sys.ltname gives the terminal name
ltt.ext[0] gives the 1st byte in table extension
