C++ (Cpp) RETURNS Examples

Example #1

File: pam_getenv.c Project: 2014-class/freerouter

const char *
pam_getenv(pam_handle_t *pamh,
	const char *name)
{
	char *str;
	int i;

	ENTERS(name);
	if (pamh == NULL)
		RETURNS(NULL);
	if (name == NULL || strchr(name, '=') != NULL)
		RETURNS(NULL);
	if ((i = openpam_findenv(pamh, name, strlen(name))) < 0)
		RETURNS(NULL);
	for (str = pamh->env[i]; *str != '\0'; ++str) {
		if (*str == '=') {
			++str;
			break;
		}
	}
	RETURNS(str);
}

Example #2

File: openpam_get_option.c Project: 2014-class/freerouter

const char *
openpam_get_option(pam_handle_t *pamh,
	const char *option)
{
	pam_chain_t *cur;
	size_t len;
	int i;

	ENTERS(option);
	if (pamh == NULL || pamh->current == NULL || option == NULL)

				RETURNS(&cur->optv[i][len]);
			else if (cur->optv[i][len] == '=')
				RETURNS(&cur->optv[i][len + 1]);
		}
	}
	RETURNS(NULL);
