strcmp function

[Anonymous]

Hi everyone,

I have been trying to compile a sample project in ObjectARX SDK (named
brsamplevc4x.dsw) and kept receiving an error: 'strcmp' : undeclared
identifier.
Could anybody tell me what was wrong with the strcmp function in the
following codes:

AcDb::SubentType subType;
char opt[128];

while (Adesk::kTrue) {
ads_printf("+AFw-nEnter Subent Type: ");
ads_initget(NULL, "Edge Face Brep");
if ((adsError = ads_getkword("Edge/Face/: ", opt))
== RTCAN) return adsError;

// Map the user input to a valid subentity type
if (strcmp(opt,"Brep") || strcmp(opt,"")) {
subType = kNullSubentType;
break;
} else if (strcmp(opt, "Face") == 0) {
subType = kFaceSubentType;
break;
} else if (strcmp(opt, "Edge") == 0) {
subType = kEdgeSubentType;
break;
}
}

Thanks,

Should you be using: AcDb:: namespaces in front of your types, i.e.:
AcDb::kNullSubentType ?

You need to make sure that string.h is #included so that the strcmp function
is declared before being used.

one silly question, did you include string.h? On which line compiler found
the error?
