πŸ’… MONGOC_GRIDFS_FILE_READV(3) πŸ’…

okay so we're deep in the libmongoc docs, and this page is all about mongoc_gridfs_file_readv(3). no cap, she reads. πŸ¦‹

πŸ“œ SYNOPSIS πŸ“œ

ssize_t
mongoc_gridfs_file_readv (mongoc_gridfs_file_t *file,
                          mongoc_iovec_t *iov,
                          size_t iovcnt,
                          size_t min_bytes,
                          uint32_t timeout_msec);

πŸŽ€ PARAMETERS πŸŽ€

  • file β€” a mongoc_gridfs_file_t. your main-character file object, periodt. πŸ‘‘
  • iov β€” an array of mongoc_iovec_t. it's giving scatter/gather realness. ✨
  • iovcnt β€” the number of elements in iov. literally how many little slots are in the array. πŸŽ€
  • min_bytes β€” the minimum number of bytes that must be read or an error will be synthesized. so if you don't get enough bytes, bestie, it's not gonna pretend everything's fine. 😭
  • timeout_msec β€” unused. she's just there, sitting pretty, not doing anything. πŸ’€

πŸ’– DESCRIPTION πŸ’–

this function performs a scattered read from file, and it can potentially block while reading from the MongoDB server. so yeah, she may make you wait a sec β€” no biggie, but don't act surprised. 🌸

the timeout_msec parameter is unused. like, completely unused. iykyk. πŸ’…

🌟 RETURNS 🌟

returns the number of bytes read, or -1 on failure. if it fails, use mongoc_gridfs_file_error() to retrieve error details. that's your little detective moment. πŸ”
