Feature querying functions
Initial version by Joost Nieuwenhuijse - joost@newhouse.nl
GPL etc..
These functions can be used to determine properties of this specific pano13 library.
Features are name/value pairs. The name is string and the value can be either an
integer, double or string. Boolean values are encoded as integers (0=false, 1=true)
Functions queryFeatureCount() and queryFeatures() can be used to obtain a list
of features. Use queryFeatureInt(), queryFeatureDouble() and queryFeatureString()
to determine the value of a specific feature. If the feature is known,
queryFeatureXxx() returns nonzero and sets the *result value.
queryFeatureString returns the string length of the feature value. The string will
be copied to the result buffer. Caller should allocate and free the result buffer.
Value is always NULL terminated (except if bufsize=0). Use
queryFeatureString(name,NULL,0) to determine the strlen of the feature value.
In addition to string values, queryFeatureString also returns the int and double
features converted into a string.
Usage:
int i,bufsize,numfeatures;
char *name;
char *value;
Tp12FeatureType type;
numfeatures=queryFeatureCount();
for(i=0; i < numfeatures;i++)
{
queryFeatures(i,&name,&type);
bufsize=queryFeatureString(name,NULL,0)+1;
value=(char*)malloc(bufsize);
queryFeatureString(name,value,bufsize);
// ... do something with the value ...
free(value);
}
