Next: tell FILEHANDLE
Attempts to write
LENGTH bytes of data from variable
SCALAR to the specified
FILEHANDLE, using the system call |
write(2). It bypasses stdio, so mixing this with reads (other than
tell() may cause confusion. Returns the number of bytes actually written, or undef if there was an error. If the length is greater than the available data, only as much data as is available will be written.
OFFSET may be specified to write the data from some part of the string other than the beginning.
OFFSET specifies writing that many bytes counting backwards from the end of the string.
