How to write a C Program to Recursive function that searches for a given file in a given folder in C Programming Language ?
Input:
- Char pointer to the path folder.
- Char pointer to the target file name.
- Char pointer to the type of file to search for.
Solution:
/* * Recursive function that searches for a given file in a given folder. * input: Char pointer to the path folder. * Char pointer to the target file name. * Char pointer to the type of file to search for. */ void find_file(char* path, char* target, char typeValue){ DIR *dir; struct dirent *entry; if (!(dir = opendir(path))){ perror("Could not open directory."); return; } while ((entry = readdir( dir )) != NULL) { if ( !strcmp( entry->d_name, "." )) continue; if ( !strcmp( entry->d_name, ".." )) continue; struct stat s; char fullpath[strlen(path) + strlen(entry->d_name) + 2]; sprintf(fullpath, "%s/%s", path, entry->d_name); lstat(fullpath, &s); // If entry is a directory - add directory to list if (S_ISDIR(s.st_mode)) { addFolderToList(fullpath); } // Switch over type value, only print matches with correct type if (strcmp(target, entry->d_name) == 0) { switch (typeValue){ case ('a'): printf("%s \n", fullpath); break; case ('d'): if (S_ISDIR(s.st_mode)) printf("%s \n", fullpath); break; case ('l'): if(S_ISLNK(s.st_mode)) printf("%s \n", fullpath); break; case ('f'): if(S_ISREG(s.st_mode)) printf("%s \n", fullpath); break; } } } closedir(dir); }
