Function Documentation

void sc_free

(

void *

pointer

)

Deallocates the memory allocation pointed to by pointer.

Parameters

pointer

The 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

error

the error to free.

Since

4.11.0

const char* sc_get_information_string

(

ScInformationKey

key

)

Get information string.

Parameters

key	information 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
