Hi, I have an application that statically links with version X of a library, libfoo, from thirdparty vendor, VENDOR1. It also links with a dynamic (shared) library, libbar, from a different thirdparty vendor, VENDOR2, that statically links version Y of libfoo from VENDOR1. So libbar.so contains version Y of libfoo.a and my executable co...
valgrind is reporting uninitialized memory errors from code like this: unsigned char buf[100]; struct driver_command cmd; cmd.len = sizeof(buf); cmd.buf = buf; ioctl(my_driver_fd, READ, &cmd); for(i = 0; i < sizeof(buf); i++) { foo(buf[i]); /* <<--- uninit use error from valgrind */ } If I memset() the buf before the driver call,...
Here is my issue. I have a std::vector<POINTFLOAT> Which stores verticies. The issue is that Vertex buffer objects take in a pointer to an array of float. Therein lies my problem. I cannot give it an array of pointfloat. Is there a way that I could instead push pointers to the individual components of each vertex without pushing in copie...
For example, in <ctype.h> there are functions like isalpha(). I want to know if writing an isalpha function on my own is faster than calling isalpha? Thanks for all your instant replies! just want to make clearer to my question: so even for the isalpha function? because you can simply pass a character and check if the character is b...
Hello, How can I read multiple lines from a text file (variable width) and store all of them in a C "string"? EDIT: I guess I'll be fget'ing the strings and storing them in one flexible buffer (via realloc) :) Also, this is not homework even though it apparently seems so (programming is just a hobby for me). I was just asking out of cu...
I've got a laser profiling system; the included software has a few bugs and missing features that I'd like to correct. I have the source code for this software which compiles but subsequently will not run. The device driver for the hardware is already installed (Windows 7 is the platform, though XP is a likely target as well); I'd like...
I have a C# VS10 project. I want its part to be pure C. So I will have pure C library and A C# file that will have part with C code calling that pure Lib. So I'll have C part of code - not precompiled DLL but C code and C# code files. So is it possible to have inside one C# file C code like we have C code inside C++ code? like Inline C...
