Enumeration Type Documentation

Describes the focus mode of a camera.

Since
4.6.0
Enumerator
SC_CAMERA_FOCUS_MODE_UNKNOWN 

the focus capabilities are not known

SC_CAMERA_FOCUS_MODE_FIXED 

the camera cannot change its focus

SC_CAMERA_FOCUS_MODE_AUTO 

the camera automatically adjusts the focus to create a sharp image

SC_CAMERA_FOCUS_MODE_MANUAL 

the camera is controlled by the user

Enumeration of different information strings.

Values of this enumeration are passed to sc_get_information_string to retrieve specific information.

Since
4.16.1

Function Documentation

void sc_free ( void *  pointer)

Deallocates the memory allocation pointed to by pointer.

Parameters
pointerThe pointer to be deallocated. In case pointer is a null pointer, no operation is performed.
void sc_error_free ( ScError error)

free's any memory associated with the error

Upon exit, the data fields are set to 0.

Parameters
errorthe error to free.
Since
4.11.0
const char* sc_get_information_string ( ScInformationKey  key)

Get information string.

Parameters
keyinformation identifier
Returns
The string associated with the given key, null if no string is associated with the key. The returned key is constant and must not be freed by the caller.
Since
4.16.1
