hi,
how does a program know whether some data are available from stdin?
I would like to make a program which could read its data from stdin
and _if_there_is_nothing_at_stdin_ from a file which name is given
as an argument. If there is nothing in stdin and no filename is given as
argument,... (2 Replies)

can you redirect STDIN with command arguments?
I have tried this approach:
# ./script -option <argument1> <argument2> 0<$2
# $2: ambiguous redirect
Is this possible? (4 Replies)
Hi,
Program A: uses pipe()
I am able to read the stdout of PROGAM B (stdout got through system() command) into PROGRAM A using:
* child
-> dup2(fd, STDOUT_FILENO);
-> execl("/path/PROGRAM B", "PROGRAM B", NULL);
* parent
-> char line;
-> read(fd, line, 100);

When a process fork(), the child share the same file descriptors as his father. Thus, they share the same stdin. Quick and dirty exemple below (sorry for the ugly gets() call) :
#include <stdio.h>
#include <unistd.h>
int main()
{
char buf;
if (fork()) { /*parent */

Bonjour,
Mon application en C sous linux tourne en redirigeant stdin vers un fichier.
Exemple; $appli1 <file1.
PB: Je voudrais temporairement redonner la main au user sur le clavier.
Alors je pensais ajouter system("appli2"); dans appli1.
Dans son main() , appli2() fait seulement un... (1 Reply)

Query Results -
Data Structures
struct globus_rls_attribute_object_t
globus_rls_client_lrc_attr_search() returns a list of these structures which include the object name (LFN or PFN) and attribute value
found by the query.
struct globus_rls_string2_t
String pair result.
struct globus_rls_string2_bulk_t
String pair result with return code, returned by bulk query operations.
Functions
globus_result_t globus_rls_client_free_list (globus_list_t *list)
Detailed Description
List results are returned as globus_list_t's, list datums depend on the type of query (eg globus_rls_string2_t, globus_rls_attribute_t,
etc).
A list result should be freed with globus_rls_client_free_list() when it's no longer needed. RLS supports limiting the number of results
returned by a single query using an offset and reslimit. The offset specifies which result to begin with, reslimit specifies how many
results to return. Offset should begin at 0 to retrieve all records. If reslimit is 0 then all results are returned at once, unless the
server has a limit on results configured. If NULL is passed as the offset argument then the API will repeatedly call the query function
until are results are retrieved. The following are equivalent examples of how to print the lfn,pfn pairs returned by
globus_rls_client_lrc_get_lfn():
globus_list_t *str2_list;
globus_list_t *p;
globus_rls_string2_t *str2;
// Retrieve all results, API will handle looping through partial results
// if the server has a limit configured. Error handling has been omitted.
globus_rls_client_lrc_get_lfn(h, "somepfn", NULL, 0, &str2_list);
for (p = str2_list; p; p = globus_list_rest(p)) {
str2 = (globus_rls_string2_t *) globus_list_first(p);
printf("lfn: %s pfn:%s0, str2->s1, str2->s2);
}
globus_rls_client_free_list(str2_list);
// This code fragment retrieves results 5 at a time. Note offset is set
// to -1 when the server has no more results to return.
int offset = 0;
while (globus_rls_client_lrc_get_lfn(h, "somepfn", &offset, 5, &str2_list) == GLOBUS_SUCCESS) {
for (p = str2_list; p; p = globus_list_rest(p)) {
str2 = (globus_rls_string2_t *) globus_list_first(p);
printf("lfn: %s pfn:%s0, str2->s1, str2->s2);
}
globus_rls_client_free_list(str2_list);
if (offset == -1)
break;
}
