ZIP_SOURCE_FILE(3) BSD Library Functions Manual ZIP_SOURCE_FILE(3) NAME zip_source_file, zip_source_file_create — create data source from a file LIBRARY libzip (-lzip) SYNOPSIS #include <zip.h> zip_source_t * zip_source_file(zip_t *archive, const char *fname, zip_uint64_t start, zip_int64_t len); zip_source_t * zip_source_file_create(const char *fname, zip_uint64_t start, zip_int64_t len, zip_error_t *error); DESCRIPTION The functions zip_source_file() and zip_source_file_create() create a zip source from a file. They open fname and read len bytes from offset start from it. If len is 0 or -1, the whole file (starting from start) is used. If the file supports seek, the source can be used to open a zip archive from. The file is opened and read when the data from the source is used, usu- ally by zip_close() or zip_open_from_source(). 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 indi- cate the error. ERRORS zip_source_file() and zip_source_file_create() fail if: [ZIP_ER_INVAL] fname, start, or len are invalid. [ZIP_ER_MEMORY] Required memory could not be allocated. [ZIP_ER_OPEN] Opening fname failed. SEE ALSO libzip(3), zip_file_add(3), zip_file_replace(3), zip_source(3) HISTORY zip_source_file() and zip_source_file_create() were added in libzip 1.0.
