Function Documentation

int fexist (  char *  path  )  [static]

check the existence of file corresponding to <path> Parameters: path  absolute filename to be checked. Return values: 1  file exists. 0  failure. Definition at line 133 of file lcmaps_utils.c. Referenced by lcmaps_getfexist().

char* lcmaps_findfile (  char *  name  )

Checks for file in standard directories. The directories that are checked are: current directory "modules" LCMAPS_ETC_HOME LCMAPS_MOD_HOME LCMAPS_LIB_HOME Parameters: name  string containing the file name Returns: pointer to a string containing the absolute path to the file, which has to be freed or NULL. Definition at line 218 of file lcmaps_utils.c. References LCMAPS_ETC_HOME, lcmaps_genfilename(), lcmaps_getfexist(), LCMAPS_LIB_HOME, and LCMAPS_MOD_HOME. Referenced by PluginInit().

char* lcmaps_genfilename (  char *  prefixp, char *  pathp, char *  suffixp )

Generate an absolute file name. Given a starting prefix, a relative or absolute path, and a suffix an absolute file name is generated. Uses the prefix only if the path is relative. (Copied (and modified) from GLOBUS gatekeeper.c) Parameters: prefixp  string containing the prefix to be prepended. pathp  relative/absolute path to file name. suffixp  string containing the suffix to be appended. Returns: pointer to a string containing the absolute path to the file, which has to be freed. Definition at line 76 of file lcmaps_utils.c. Referenced by lcmaps_findfile(), lcmaps_setup(), and startPluginManager().

int lcmaps_get_gidlist (  const char *  username, int *  ngroups, gid_t **  group_list )

Finds the list of gids for user in the group file (/etc/group). Returns a list of gid_t which should be freed by calling program. Parameters: username  the name of the user ngroups  ptr to int which will be filled with the number of gids group_list  ptr to an array of gid_t Return values: 0  success -1  realloc failure -2  getgrent failure 1  failure Definition at line 407 of file lcmaps_utils.c. References lcmaps_log(), and lcmaps_log_debug().

char* lcmaps_getfexist (  int  n, ...  )

Picks the first existing file in argument list. Parameters: n  the number of paths presented in the following argument list. ...  variable argument list of paths. Returns: filename found or NULL Definition at line 176 of file lcmaps_utils.c. References fexist(). Referenced by lcmaps_findfile().

int lcmaps_tokenize (  const char *  command, char **  args, int *  n, char *  sep )

Break the argument string up into tokens. Breakup the command in to arguments, pointing the args array at the tokens. Replace white space at the end of each token with a null. A token maybe in quotes. (Copied (and modified) from GLOBUS gatekeeper.c) Parameters: command  the command line to be parsed args  pointer to an array of pointers to be filled n  size of the array, on input, and set to size used on output sep  string of separating characters Return values: 0  succes -1  malloc error -2  too many args -3  quote not matched Definition at line 292 of file lcmaps_utils.c. Referenced by lcmaps_setup(), and parse_args_plugin().
