Hello i'm trying to use PVFS_sys_read function but i can't understand what the following arguments mean:
ret = PVFS_sys_read(src->u.pvfs2.ref, file_req, offset,buffer, mem_req, credentials, &resp_io, hints);
1. size_t count --> What does 'count' mean?What value shall i place here?I can't understand the meaning of count2. char * buffer --> what does it store?3. int64_t offset --> what does it mean?
I can't understand what these arguments do and what values can be assigned to them.
eg. Is buffer the array where the line of the file is going to be stored?
Thanks, in advance
