The kva_match() function searches a kva_t structure, which is part of the authattr_t, execattr_t, profattr_t, or userattr_t structures. The function takes two arguments: a pointer to a key value array, and a key. If the key is in the array, the function returns a pointer to the first corresponding value that matches that key. Otherwise, the function returns NULL.

Upon successful completion, the function returns a pointer to the value sought. Otherwise, it returns NULL.

The kva_match() function returns a pointer to data that already exists in the key-value array. It does not allocate its own memory for this pointer but obtains it from the key-value array that is passed as its first argument.
