explain_pathconf_or_die − get configuration values and report errors
#include <libexplain/pathconf.h>
long explain_pathconf_or_die(const char *pathname, int name);
The explain_pathconf_or_die function is used to call the pathconf(3) system call. On failure an explanation will be printed to stderr, obtained from explain_pathconf(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
long value = explain_pathconf_or_die(pathname, name);
Note that a −1 return value is still possible, meaning the system does not have a limit for the requested resource.
pathname
The pathname, exactly as to be passed to the pathconf(3) system call.
name |
The name, exactly as to be passed to the pathconf(3) system call. |
Returns:
This function only returns on success. On failure, prints an explanation and exits.
get configuration values for files
explain pathconf(3) errors
terminate the calling process |
