ZIP_SOURCE_SEEK(3) Library Functions Manual ZIP_SOURCE_SEEK(3)

set read offset in zip source

libzip (-lzip)

#include <zip.h>

zip_source_seek(zip_source_t *source, zip_int64_t offset, int whence);

The function zip_source_seek() sets the current read offset for source. Just like in fseek(3), depending on the whence argument, the offset is counted relative from:
start of file
current read offset in file
end of file

Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in source is set to indicate the error.

zip_source_seek() was added in libzip 1.0.
