Earth transform projection and sensor attributes are stored in datasets as integer codes. Projection and sensor codes are listed in include/etx.h. Projection and sensor names are defined in include/etnames.h.
projcode and sensorcode return codes corresponding to given projection and sensor names, respectively.
projname and sensorname return names corresponding to given projection and sensor codes, respectively.
If successful, projcode and sensorcode return valid non-negative codes. Otherwise, they return -1 and set terrno to the appropriate error code.
If successful, projname and sensorname return pointers to projection and sensor names, respectively. Otherwise, they return NULL and set terrno to the appropriate error code.
