zip_fopen , - .Nm zip_fopen_index open file in zip archive for reading
#include <zip.h> struct zip_file * zip_fopen(struct zip *archive, const char *fname, int flags); struct zip_file * zip_fopen_index(struct zip *archive, zip_uint64_t index, int flags);
The zip_fopen function opens the file name fname in archive. The flags argument specifies how the name lookup should be done, according to the values are described in zip_name_locate(3). Also, the following values may be or'ed to it. ZIP_FL_COMPRESSED Read the compressed data. Otherwise the data is uncompressed by zip_fread. ZIP_FL_UNCHANGED Read the original data from the zip archive, ignoring any changes made to the file. The zip_fopen_index function opens the file at position index. If encrypted data is encountered, the functions call zip_fopen_encrypted(3) or zip_fopen_index_encrypted(3) respectively, using the default password set with zip_set_default_password(3).
Upon successful completion, a struct zip_file pointer is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error.
[ZIP_ER_CHANGED] The file data has been changed. [ZIP_ER_COMPNOTSUPP] The compression method used is not supported. [ZIP_ER_ENCRNOTSUPP] The encryption method used is not supported. [ZIP_ER_MEMORY] Required memory could not be allocated. [ZIP_ER_READ] A file read error occurred. [ZIP_ER_SEEK] A file seek error occurred. [ZIP_ER_ZLIB] Initializing the zlib stream failed. The function zip_fopen may also fail and set for any of the errors specified for the routine zip_name_locate(3). The function zip_fopen_index may also fail with ZIP_ER_INVAL if index is invalid.
