Dos16QueryModFromCS

Dos16QueryModFromCS queries the name, segment, and handle that corresponds to a 16 bit selector. It takes a selector as a parameter and returns information about the module (a protect mode application currently executing) owning that selector.

Syntax
Dos16QueryModFromCS (sel, qmresult)

Parameters
typedef struct_QMRESULT{USHORT seg; USHORT htme; char name[256];} QMRESULT; typedef QMRESULT*PQMRESULT;
 * sel (SEL) input : Selector to be queried.
 * qmresult (QMRESULT) output : Structure containing the queried information

Return Code
ulrc (APIRET) returns Dos16QueryModFromCS returns one of the following values
 * 0 NO_ERROR
 * 87 ERROR_INVALID_PARAMETER

Example Code

 * 1) define INCL_DOSMODULEMGR
 * 2) include 

int main(int argc, char *argv[], char *envp[]){ SEL sel=0; QMRESULT qmresult; APIRET16 rc;

if (argc!=2) { printf("QMODCS sel\n"); return; } /* endif */

sel=(SEL)strtoul(argv[1],NULL,16);

rc=Dos16QueryModFromCS(sel, qmresult);

if (rc != 0) { printf("DosQueryModFromCS returned rc=%u\n",rc); return rc; } /* endif */

printf("Sel=0x%04x Handle=0x%04x Segment=0x%04x %s\n",          sel,qmresult.hmte,qmresult.seg,qmresult.name);

return 0; }
