The given offset is the 21 exact number of bytes that are skipped, counting from the beginning of the 22 source file before it is transferred to the destination. If used with uploads, 23 the FTP server command SIZE is not used by curl. 24 25 Use "-C -" to instruct curl to automatically find out where/how to resume the 26 transfer. It then uses the given output/input files to figure that out. 27 28 When using this option for HTTP uploads using POST or PUT, functionality is 29 not guaranteed. The HTTP protocol has no standard interoperable resume upload 30 and curl uses a set of headers for this purpose that once proved working for 31 some servers and have been left for those who find that useful. 32 33 This command line option is mutually exclusive with --range: you can only use 34 one of them for a single transfer. 35 36 The --no-clobber and --remove-on-error options cannot be used together with 37 --continue-at.
