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.
