c - File Path to in memory file -

i have void *buffer instance of file in ram.

the file type in format must parsed api given.

unfortunately, way open file type through api supply api file path:

sample_api_open(char *file_name, ...); 

i understand shm_open returns file descriptor, api takes file path.

is there work around read type of file in memory?

instead of using posix shared memory, open temporary file , mmap() it. make buffer end in mmap()-ed region can call api on temporary file.
