You made it an array of arrays, guaranteeing it will never be NULL. array[j] just calculates array + (j*50), which isn't going to be zero.
If you want to store a null pointer, you'll have to store pointers. Then you get address stored at (base_address + j) which is quite capable of being NULL.
Hello, sorry if this has been posted before but i was wondering if there is a way to run a program until a segmentation fault is found.
Currently i'm using a simple shell script which runs my program 100 times, sleeps 1 second because srand(time(0)) is dependent on seconds. Is there a possible... (1 Reply)
Hello everyone,
I'm writing a program using the id3lib unfortunately I've encountered with memory issue that cause segmentation fault. I tried to rerun and analyze the program with valgrind but it doesn't point me anywhere. I really stuck on this one.

It is my first post, hoping to get help from the forum.

I have a program that allows users to specify the debug log file location and name.
I have tried using the access() and stat() but they both segfault if the drive say (d:\) is invalid. Both seem to be fine if the drive exists.
Could someone please point me in the direction to a function that... (1 Reply)
hello all,
my question is not about How code can be rewritten, i just wanna know even though i am not using read only memory of C (i have declared str) why this function gives me segfault :wall:and the other code executes comfortably though both code uses same pointer arithmetic.

I have an array and two variables as below,
I need to check if $datevar is present in $filename.
If so, i need to replace $filename with the values in the array.

Another project, another bump in the road and another chance to learn. I've been trying to open gzipped files and parse data from them and hit a snag. I have data in gzips with a place followed by an ip or ip range sort of like this:

GLSHADERSOURCE(3G) OpenGL Manual 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
