I've been wondering if I can make mutexes much easier to use in C++ with creative use of a locking class and variable scope, but I'm not sure if things happen in the order I want. Here's pseudocode for something that could use the class:
int someclass::getvalue()
{
int retval;

Hi,
I am stuck while developing a shell sub-routine which checks the log file for "success" or "failure". The subroutine reads the log file and checks for key word "success", if found it set the variable (found=1). It returns success or failure based on this variable.
My problem is, I can... (2 Replies)
Hi all,
I have this scenario where:-

$ ls *trx
my.08120323.trx

I am new to unix shell scripting,
in the below script "num" is an input file which contains a series of numbers example :

Hi,
I want to know about the variable scope in shell script.
How can we use the script argument inside the function?
fn () {
echo $1 ## I want this argument should be the main script argument and not the funtion argument.
}
also are there any local,global types in shell script?

Hi All,
I've been researching this problem and I am pretty sure that the issue is related to the while loop and the piping. There are plenty of other threads about this issue that recommend removing the pipe and using redirection. However, I haven't been able to get it working using the ssh and... (1 Reply)
Hi,
I use Korn Shell. Searched Forum and modified the way the file is input to the while loop, but still the variable does not seem to be retaining the final count.

Hi,
I'm a Delphi developer new to linux, new to this forums and new to BASH programming and got a new task in my work: maintaining an existing set of BASH scripts. First thing I want to do is making the code more reliable as in my opinion it's really bad written. So here's the quest:

gluendtrim
GLUBEGINTRIM(3G)GLUBEGINTRIM(3G)NAME
gluBeginTrim, gluEndTrim - delimit a NURBS trimming loop definition
C SPECIFICATION
void gluBeginTrim( GLUnurbs* nurb )
void gluEndTrim( GLUnurbs* nurb )
PARAMETERS
nurb Specifies the NURBS object (created with gluNewNurbsRenderer).
DESCRIPTION
Use gluBeginTrim to mark the beginning of a trimming loop, and gluEndTrim to mark the end of a trimming loop. A trimming loop is a set of
oriented curve segments (forming a closed curve) that define boundaries of a NURBS surface. You include these trimming loops in the defini-
tion of a NURBS surface, between calls to gluBeginSurface and gluEndSurface.
The definition for a NURBS surface can contain many trimming loops. For example, if you wrote a definition for a NURBS surface that resem-
bled a rectangle with a hole punched out, the definition would contain two trimming loops. One loop would define the outer edge of the rec-
tangle; the other would define the hole punched out of the rectangle. The definitions of each of these trimming loops would be bracketed by
a gluBeginTrim/gluEndTrim pair.
The definition of a single closed trimming loop can consist of multiple curve segments, each described as a piecewise linear curve (see
gluPwlCurve) or as a single NURBS curve (see gluNurbsCurve), or as a combination of both in any order. The only library calls that can
appear in a trimming loop definition (between the calls to gluBeginTrim and gluEndTrim) are gluPwlCurve and gluNurbsCurve.
The area of the NURBS surface that is displayed is the region in the domain to the left of the trimming curve as the curve parameter
increases. Thus, the retained region of the NURBS surface is inside a counterclockwise trimming loop and outside a clockwise trimming loop.
For the rectangle mentioned earlier, the trimming loop for the outer edge of the rectangle runs counterclockwise, while the trimming loop
for the punched-out hole runs clockwise.
If you use more than one curve to define a single trimming loop, the curve segments must form a closed loop (that is, the endpoint of each
curve must be the starting point of the next curve, and the endpoint of the final curve must be the starting point of the first curve). If
the endpoints of the curve are sufficiently close together but not exactly coincident, they will be coerced to match. If the endpoints are
not sufficiently close, an error results (see gluNurbsCallback).
If a trimming loop definition contains multiple curves, the direction of the curves must be consistent (that is, the inside must be to the
left of all of the curves). Nested trimming loops are legal as long as the curve orientations alternate correctly. If trimming curves are
self-intersecting, or intersect one another, an error results.
If no trimming information is given for a NURBS surface, the entire surface is drawn.
EXAMPLE
This code fragment defines a trimming loop that consists of one piecewise linear curve, and two NURBS curves:
gluBeginTrim(nobj);
gluPwlCurve(..., GLU_MAP1_TRIM_2);
gluNurbsCurve(..., GLU_MAP1_TRIM_2);
gluNurbsCurve(..., GLU_MAP1_TRIM_3); gluEndTrim(nobj);
