ZIP_SOURCE_FILEP(3)

NAME
zip_source_filep, zip_source_filep_create - create data source from FILE *

LIBRARY
libzip (-lzip)

SYNOPSIS
#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);

DESCRIPTION
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).

RETURN VALUES
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.

ERRORS
zip_source_filep() fails if:

[ZIP_ER_INVAL]
    file, start, or len are invalid.

[ZIP_ER_MEMORY]
    Required memory could not be allocated.
