Hi,
when I execute a script on unix AIX, I've got an error message:
"Execution: 85328 Signal d'alarme".
If I edit this file with "vi", I ve got the same error after a while (about 1 minute).
If I try with another user I still have the problem.
But if I rename this file, no problem.

I am trying to write a signal to exit when a process times out. What I have come up with from poking around the web is this.

Is it ok to use exit() inside a signal handler?
I catch SIGUSR1 in a signal handler and I try to close a file and then exit. The result is inconsistent. Sometimes the process exit and sometimes it returns to the original state before the signal handler was invoked.
Perhaps exit is not legal in... (8 Replies)

I'm writing a function right now, and I want to set an alarm to avoid a timeout, here's the general idea of my code:
int amt = -2;
alarm(10);
amt = read(fd, &t->buf, TASKBUFSIZ - tailpos); //do a read
when the alarm goes off, i want to check the value of "amt"

Our small company, about 5 users, need a basic script that scans mapped network drives (example: drive b,c,d, e, and f) for hard drive usage. This needs to send a report to myself in any type of basic notepad format (easy to read and decipher) for drives that have reached 80% usage... any ideas? ... (1 Reply)
Hi,
A basic sed question.
I have a set of files. In each file there is a number that I want replaced. For example, if I run sed I should get the following:
% cat test2.txt
#goofy//171.00
goofy 171.00
% sed -i 's/171/xxx/g' test2.txt
% cat test2.txt
#goofy//xxx.00
goofy xxx.00

FunImageRowGet - get row(s) of an image
SYNOPSIS
#include <funtools.h>
void *FunImageRowGet(Fun fun, void *buf, int rstart, int rstop,
char *plist)
DESCRIPTION
The FunImageRowGet() routine returns one or more image rows from the specified section of a Funtools data file. If the input data are of
type image, the array is generated by extracting the specified image rows and then binning them according to the specified bin factor. If
the input data are contained in a binary table or raw event file, the rows are binned on the columns specified by the bincols= keyword
(using appropriate default columns as needed), after which the image section and bin factors are applied.
The first argument is the Funtools handle returned by FunOpen(). The second buf argument is a pointer to a data buffer to fill. If NULL is
specified, FunImageGet() will allocate a buffer of the appropriate size.
The third and fourth arguments specify the first and last row to retrieve. Rows are counted starting from 1, up to the value of
FUN_YMAX(fun). The final plist (i.e., parameter list) argument is a string containing one or more comma-delimited keyword=value parame-
ters. It can be used to specify the return data type using the bitpix= keyword. If no such keyword is specified in the plist string, the
data type of the image is the same as the data type of the original input file, or is of type int for FITS binary tables.
If the bitpix=value is supplied in the plist string, the data type of the returned image will be one of the supported FITS image data
types:
o 8 unsigned char
o 16 short
o 32 int
o -32 float
o -64 double
For example:
double *drow;
Fun fun;
... open files ...
/* get section dimensions */
FunInfoGet(fun, FUN_SECT_DIM1, &dim1, FUN_SECT_DIM2, &dim2, 0);
/* allocate one line's worth */
drow = malloc(dim1*sizeof(double));
/* retrieve and process each input row (starting at 1) */
for(i=1; i <= dim2; i++){
if( !FunImageRowGet(fun, drow, i, i, "bitpix=-64") )
gerror(stderr, "can't FunImageRowGet: %d %s
", i, iname);
/* reverse the line */
for(j=1; j<=dim1; j++){
... process drow[j-1] ...
}
}
...
On success, a pointer to the image buffer is returned. (This will be the same as the second argument, if NULL is not passed to the latter.)
On error, NULL is returned. Note that the considerations described above for specifying binning columns in FunImageGet() also apply to
FunImageRowGet().
