Size of a socket length parameter​.
typedef unsigned char globus_byte_t

Typedef Documentation

typedef int globus_bool_tBoolean type​. Set values to either the constant GLOBUS_TRUE and GLOBUS_FALSE

typedef uint32_t globus_result_tWeak pointer to a Globus Error object, or the special value GLOBUS_SUCCESS

typedef socklen_t globus_socklen_tSize 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​.

Function Documentation

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​.

int globus_tilde_expand (unsigned long options, globus_bool_t url_form, char * inpath, char ** outpath)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​.
