NAME
zzip_entry_data_offset, zzip_entry_fread_file_header, zzip_entry_strdup_name - helper functions for (fseeko) zip access apiSYNOPSIS
#include <zzip/fseeko.h>
-
zzip_off_t zzip_entry_data_offset((ZZIP_ENTRY * entry));
- static zzip_off_t zzip_entry_fread_file_header((ZZIP_ENTRY * entry, struct zzip_file_header *file_header));
- zzip__new__ char * zzip_entry_strdup_name((ZZIP_ENTRY * entry));
- static zzip_off_t zzip_entry_fread_file_header((ZZIP_ENTRY * entry, struct zzip_file_header *file_header));
DESCRIPTION
The zzip_entry_fread_file_header functions read the correspoding struct zzip_file_header from the zip disk of the given "entry". The returned off_t points to the end of the file_header where the current fseek pointer has stopped. This is used to immediatly parse out any filename/extras block following the file_header. The return value is null on error.
The zzip_entry_strdup_name function is a big helper despite its little name: in a zip file the encoded filenames are usually NOT zero-terminated but for common usage with libc we need it that way. Secondly, the filename SHOULD be present in the zip central directory but if not then we fallback to the filename given in the file_header of each compressed data portion.
