Problem in compiling in linux

ptr=strrchr(path,'\\');

strncpy(path1,path,ptr-path);

path1[ptr-path]='\0';

strcat(path1,"\\file.txt");

output_file=fopen(path1,"w");
here path is some path of an input file. this code works fine for me in borlandc. when i use gcc it shows "Segmentation fault (core dumped)" error.

My guess is that you don't find the correct file because you are using \\ instead of / in your file-path. Backslash is how MS splits paths, whilst Unix/Linux uses forward slashes.
