NAME

zip_source_seek_compute_offset − validate arguments and compute offset

LIBRARY

libzip (-lzip)

SYNOPSIS

#include <zip.h>

zip_int64_t

zip_source_seek_compute_offset(zip_uint64_t offset, zip_uint64_t length, void *data, zip_uint64_t data_length, zip_error_t *error);

DESCRIPTION

Use this function to compute the offset for a ZIP_SOURCE_SEEK or ZIP_SOURCE_SEEK_WRITE command. data and data_length are the arguments to the source callback, offset is the current offset and length is the length of the source data or, for ZIP_SOURCE_SEEK_WRITE, the amount of data written.

RETURN VALUES

On success, it returns the new offset, on error it returns −1 and sets error.

ERRORS

zip_source_seek_compute_offset() fails if:

[ZIP_ER_INVAL]

One of the arguments is invalid or the seek would place the offset outside the data.

SEE ALSO

zip_source_function(3)

HISTORY

zip_source_seek_compute_offset() was added in libzip 1.0.
