I'm using Bison & Flex for 1 month more or less, so I'm sorry if I don't see something obvious (but I don't think it is). I have a problem about freeing memory with Flex Bison. Here is what my...

I want to use POSIX's basename function (as opposed to GNU's). From the man page: Both dirname() and basename() may modify the contents of path, so it may be desirable to pass a copy when call...

Does strdup allocate another memory zone and create another pointer every time? For example: does the following code result in a memory leak? void x(char** d, char* s){ *d = strdup(s); } int ma...

I am calling strdup and have to allocate space for the variable before calling strdup. char *variable; variable = (char*) malloc(sizeof(char*)); variable = strdup(word); Am I doing this right? O...
