zip_source_filep

zip_source_filep, zip_source_filep_create —
create data source from FILE *

libzip (-lzip)

#include <zip.h>

zip_source_t *
zip_source_filep(zip_t *archive, FILE *file, zip_uint64_t start, zip_int64_t len);

zip_source_t *
zip_source_filep_create(FILE *file, zip_uint64_t start, zip_int64_t len, zip_error_t *error);

The functions zip_source_filep() and zip_source_filep_create() create a zip source from a file stream. They read len bytes from offset start from the open file stream file. For a description of the len argument, see zip_source_file(3).

If the file stream supports seeking, the source can be used to open a read-only zip archive from.

The file stream is closed when the source is being freed, usually by zip_close(3).

Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive or error is set to indicate the error.

zip_source_filep() fails if:
[]
file, start, or len are invalid.
[]
Required memory could not be allocated.
