zip_source_filep(3) Library Functions Manual 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.
