Retrieve the current value of the specified context property of type char
Synopsis:
#include <screen/screen.h>
int screen_get_context_property_cv(screen_context_t ctx,
int pname,
int len,
char *param)
Arguments:
ctx
The handle of the context whose property is being queried.
pname
The name of the property whose value is being queried. The properties available for query are of type Screen property types.
len
The maximum number of bytes that Screen can write to param.
param
The buffer where Screen stores the retrieved value (a character array that includes a terminating null character). This buffer must be an array of type char with a minimum length of len. If this user-provided buffer has insufficient space for storing the property being retrieved, Screen truncates the retrieved value and returns the character array without a terminating null character.
