Function Documentation

int check_argument (  const char *  name, char **  value, unsigned int  num, int  argc, char *  argv[], int *  pos )

check_argument(name, value, num, argc, argv, pos) Check if the name matches the argument at position pos. If it does, then depending if num is equal to zero or one, zero or one values are read and stored at value. Parameters: name  Name to be matched. value  store the value, may not be NULL! num  Number of args to be read, following a match. argc  Argc variable. argv  Argv variable. pos  Current possition in the argv list. Returns: 1 if successfull, 0 otherwise. Definition at line 212 of file lcmaps_afs.c. References lcmaps_log(), LCMAPS_MOD_FAIL, and LCMAPS_MOD_SUCCESS.

int construct_argv (  char *  cmd, char **  argv[] )

construct_arfv(cmd, argv) Construct an argv list. The first element is the name of the executable. Parameters: cmd  command to be executed, this will be argv[0]. argv  pointer that hold the location of argv[] pointer. Returns: 1 if successfull, 0 otherwise. Definition at line 390 of file lcmaps_afs.c. References lcmaps_log(), and lcmaps_log_debug().

void destruct_argv (  char **  argv[]  )

destruct_argv(argv) Destruct the argv list by freeing all elements as well as the list itself. Parameters: argv  argv list to be freed. Definition at line 441 of file lcmaps_afs.c.

int fail_afs (  void   )

fail_afs(void) Do some necessary cleanup when the afs plugin fails. Definition at line 573 of file lcmaps_afs.c. References LCMAPS_MOD_FAIL.

int run_cmd (  char *  cmd, char *  argv[] )

run_cmd(cmd, argv) Run a command. The standard output and standard error are piped back into the current process and appended to the logging of the current process. Definition at line 464 of file lcmaps_afs.c. References lcmaps_log(), and lcmaps_log_debug().
