Globus Common API Common Data Structures and Functions.


#define GLOBUS_COMMON_MODULE (&globus_i_common_module)
Globus Common Module Descriptor. #define GLOBUS_TILDE_EXPAND
Expand ~. #define GLOBUS_TILDE_USER_EXPAND
Expand ~user. #define GLOBUS_TRUE 1
True value for globus_bool_t. #define GLOBUS_FALSE 0
False value for globus_bool_t. #define GLOBUS_SUCCESS 0
Generic success result

Most Globus API functions return this value to indicate success, or some error constant or globus_result_t to indicate an error. " #define GLOBUS_FAILURE -1
Generic failure result

Some Globus API functions without good error handling return this value to indicate some undetermined error occurred. "


typedef size_t globus_size_t
Standard size of memory object

The globus_size_t is the size of a memory object. It is identical to size_t in all cases and doesn't need to be used ever. " typedef socklen_t globus_socklen_t
Size of a socket length parameter. typedef unsigned char globus_byte_t
Unsigned byte datatype

This is used for byte-addressable arrays of arbitrary data which is not subject to sign extension. " typedef int globus_bool_t
Boolean type. typedef uint32_t globus_result_t


globus_result_t globus_eval_path (const char *pathstring, char **bufp)
int globus_tilde_expand (unsigned long options, globus_bool_t url_form, char *inpath, char **outpath)
Expand ~ and/or ~user in path strings.

Boolean type. Set values to either the constant GLOBUS_TRUE and GLOBUS_FALSE

Weak pointer to a Globus Error object, or the special value GLOBUS_SUCCESS

Size of a socket length parameter. The globus_socklen_t type is part of the POSIX socket interface and is also available in winsock2.h. In older UNIX implementations, this was variously a size_t or an int.

globus_result_t globus_eval_path (const char * pathstring, char ** bufp)

Parameters:

pathstring A string containing any number of variable path references using the syntax ${PATH-NAME} Supported path elements are
  • prefix
  • exec_prefix
  • sbindir
  • bindir
  • libdir
  • libexecdir
  • includedir
  • datarootdir
  • datadir
  • mandir
  • sysconfdir
  • sharedstatedir
  • localstatedir
  • perlmoduledir These strings are based on the parameters passed to this package configure script, but modified so that if GLOBUS_LOCATION is set in the environment, it is used instead of the configured path.

bufp Pointer to be set to a newly allocated string that has recursively resolved all substitution paths.

Expand ~ and/or ~user in path strings. Expand the leading ~ (or ~user) characters from inpath to the home directory path of the current user (or user specified in ~user); the result is stored in a newly allocated buffer *outpath (which will need to be freed by a call to globus_free.) The string following the ~/or ~user/ is copied verbatim to the output string.

Parameters:

options The expansion is conditioned by the options as defined in globus_tilde_expand.h:
  • GLOBUS_TILDE_EXPAND: expand ~
  • GLOBUS_TILDE_USER_EXPAND: expand ~user Otherwise, the corresponding form is not expanded (just copied int the output path)

url_form True if the inpath follows an URL format (/~) Used when expanding an url (for : <scheme>://host[:port][/path] were /path can be of the form /~[user][/...]. Otherwise, the form ~[user][/...] is expected.
inpath Input string to expand.
outpath Output string; Need to be freed when not used anymore.
