how would i use fopen() to accept an argument from a function (c programming) -

example:

void readdoc(file *doc_file) { }

how can fopen read doc_file when notation requires know document name before hand because in case file name argument in readdoc function.

you don't need fopen because fopen used open file , homecoming file* file. in code have shared, seem have file* parameter. need utilize read (fread,fscanf,fgets etc.) functions read file. however, need ensure fopen called on file need read , file* returned passed readdoc function.

c fopen
