Libsmr
LibSmr is the C programming library that enables C programs to communicate with the SMR sensor daemon, [smrd].
The library provides two types of functions: smr specific and low level.
Smr specific functions
The library provides four C functions: smr_connect(), smr_disconnect(), smr_read() and smr_write(). These are modelled after similarly named functions familiar to C programmers, used for other kinds of input/output.
Central to all use of the smr specific functions if a struct smr datatype. A pointer to such a struct is returned by smr_connect(), and this pointer is used in all subsequent calls to smr_read() and smr_write(), and must finally be provided to smr_close().
To use the library, a header file must be included. The following summary shows the function type declarations:
#include <smr.h>
struct smr *smr_connect(char *hostname, int port);
void smr_disconnect(struct smr *robot);
int smr_read(struct smr *robot);
int smr_write(struct smr *robot);
Each function, and the smr struct datatype, is described on its own page.
Low level functions
The low level functions are not currently documented.
