I am facing a strange error while creating posix threads:
Given below are two snippets of code, the first one works whereas the second one gives a garbage value in the output.
Snippet 1
This works:
--------------
int *threadids;
threadids = (int *) malloc (num_threads * sizeof(int));

there seems not to be error in this segment. In some computers, it can work well. But in others, it will give a failure.
why it ocurrs and how to deal with it?
in a function:
if( *ver == NULL ) {
*ver = (vertex *) malloc(sizeof(vertex)); //this line

Hi every body
I have a problem like that "Dynamic linker error" message.
I can't load many of programs in sco unix openserver 5.0.6.
I guess this problem appear after my last effort to install "SCO Development System" package.
How can I fix this problem?
would you please help me ? (1 Reply)
Hi everyone
I am developing an utility.
At some part of it I read directory entries to a dynamic array: struct list
It stores pointers to items: list.entries,
which are structures: struct entry
If a number of files in a directory is greater then number of elements an array was initially... (11 Replies)
Hi All,
I have a simple code which does some computation by matching string patterns.
In brief:
1. The code reads .dat and .txt files.
2. .dat files are huge text files and .txt files contain some important words.
3. I am just doing strstr to find the patterns.
4. The function returns the... (3 Replies)

I am facing a problem of memory corruption. The loop runs for the first time but does not go through the second time. What could be the problem?

GLSHADERSOURCE(3G) OpenGL 3.3 GLSHADERSOURCE(3G)NAME
glShaderSource - Replaces the source code in a shader object
C SPECIFICATION
void glShaderSource(GLuint shader, GLsizei count, const GLchar **string, const GLint *length);
PARAMETERS
shader
Specifies the handle of the shader object whose source code is to be replaced.
count
Specifies the number of elements in the string and length arrays.
string
Specifies an array of pointers to strings containing the source code to be loaded into the shader.
length
Specifies an array of string lengths.
DESCRIPTION
glShaderSource sets the source code in shader to the source code in the array of strings specified by string. Any source code previously
stored in the shader object is completely replaced. The number of strings in the array is specified by count. If length is NULL, each
string is assumed to be null terminated. If length is a value other than NULL, it points to an array containing a string length for each of
the corresponding elements of string. Each element in the length array may contain the length of the corresponding string (the null
character is not counted as part of the string length) or a value less than 0 to indicate that the string is null terminated. The source
code strings are not scanned or parsed at this time; they are simply copied into the specified shader object.
NOTES
OpenGL copies the shader source code strings when glShaderSource is called, so an application may free its copy of the source code strings
immediately after the function returns.
ERRORS
GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.
GL_INVALID_OPERATION is generated if shader is not a shader object.
GL_INVALID_VALUE is generated if count is less than 0.
ASSOCIATED GETS
glGetShader() with arguments shader and GL_SHADER_SOURCE_LENGTH
glGetShaderSource() with argument shader
