Dear Friends,
I write a c program to list the directories recursively. For this I write a function called my_readdir to read the content of directory. For this I use read system call it returns -1, then I use readdir system call it gives comment terminated error or segmentation... (1 Reply)

hi,
where can I find the detail information about the syscall in binary instructions of linux/mips.
for example, in linux/mips:

it's a syacall of "lseek" , but how can I find that which registers will be used in this syscall , and the meaning of the arguments in the... (2 Replies)
Hi All,
My application gets hang at the popen statement in Soalris 5.8. While debugging I found that it halts at _lwp_sema_wait. After googling I have added /usr/lib/lwp in the LD_LIBRARY_PATH and now it halts at lwp_park. Please help me what I need to do to solve this issue. The application runs... (6 Replies)
hello all,
I have developed a server application in C for ulinux kernel 2.6.It works very fine; creating a socket, binding it to a port, listening for incoming sockets and accepting them ,all finish without any error.

The following code:
int fd;
if (fd = open("mem", O_RDONLY) == -1)
return 1;

char *buf = malloc(512);
buf = strerror(errno);
printf("%s\n", buf);
return 1;
}
always returns with "illegal seek"... (2 Replies)

GLULOADSAMPLINGMATRICES(3G)GLULOADSAMPLINGMATRICES(3G)NAME
gluLoadSamplingMatrices - load NURBS sampling and culling matrices
C SPECIFICATION
void gluLoadSamplingMatrices( GLUnurbs* nurb,
const GLfloat *model,
const GLfloat *perspective,
const GLint *view )
PARAMETERS
nurb Specifies the NURBS object (created with gluNewNurbsRenderer).
model Specifies a modelview matrix (as from a glGetFloatv call).
perspective Specifies a projection matrix (as from a glGetFloatv call).
view Specifies a viewport (as from a glGetIntegerv call).
DESCRIPTION
gluLoadSamplingMatrices uses model, perspective, and view to recompute the sampling and culling matrices stored in nurb. The sampling
matrix determines how finely a NURBS curve or surface must be tessellated to satisfy the sampling tolerance (as determined by the
GLU_SAMPLING_TOLERANCE property). The culling matrix is used in deciding if a NURBS curve or surface should be culled before rendering
(when the GLU_CULLING property is turned on).
gluLoadSamplingMatrices is necessary only if the GLU_AUTO_LOAD_MATRIX property is turned off (see gluNurbsProperty). Although it can be
convenient to leave the GLU_AUTO_LOAD_MATRIX property turned on, there can be a performance penalty for doing so. (A round trip to the GL
server is needed to fetch the current values of the modelview matrix, projection matrix, and viewport.)
