5.4.10. SYS_SEEK (0x0A)

Seeks to a specified position in a file using an offset specified from the start of the file. The file is assumed to be a byte array and the offset is given in bytes.


On entry, r1 contains a pointer to a two-word data block:

word 1

This is a handle for a seekable file object.

word 2

This is the absolute byte position to be sought to.


On exit, r0 contains:

  • 0 if the request is successful

  • A negative value if the request is not successful. SYS_ERRNO can be used to read the value of the host errno variable describing the error.


The effect of seeking outside the current extent of the file object is undefined.
