Obtaining Libcox objects values.


These routines are used to extract values from the libcox_value objects obtained by a prior successful call to libcox_exec or inside a foreign command. Please note that if the libcox_value is not of the expected type, an automatic cast will be performed.

The libcox_value_to_string() interface takes an optional parameter (int *pLen) which is set (if not NULL) to the string length. Also note, this function return a null terminated string and does never return the NULL pointer.

Please pay particular attention to the fact that the pointer returned from libcox_value_to_string() can be invalidated by subsequent call to libcox_value_to_int(), libcox_value_to_bool(), libcox_value_to_int64() or libcox_value_to_double().



A pointer to a libcox value.
