#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);

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.
