zip_stat(3) BSD Library Functions Manual zip_stat(3)
NAME
zip_stat, zip_stat_index -- get information about file
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h> int zip_stat(zip_t *archive, const char *fname, zip_flags_t flags, zip_stat_t *sb); int zip_stat_index(zip_t *archive, zip_uint64_t index, zip_flags_t flags, zip_stat_t *sb);
DESCRIPTION
The zip_stat() function obtains information about the file named fname in archive. The flags argument specifies how the name lookup should be done. Its values are described in zip_name_locate(3). Also, ZIP_FL_UNCHANGED may be or'ed to it to request information about the original file in the archive, ignoring any changes made. The zip_stat_index() function obtains information about the file at posi- tion index. The sb argument is a pointer to a struct zip_stat (shown below), into which information about the file is placed. struct zip_stat { zip_uint64_t valid; /* which fields have valid values */ const char *name; /* name of the file */ zip_uint64_t index; /* index within archive */ zip_uint64_t size; /* size of file (uncompressed) */ zip_uint64_t comp_size; /* size of file (compressed) */ time_t mtime; /* modification time */ zip_uint32_t crc; /* crc of file data */ zip_uint16_t comp_method; /* compression method used */ zip_uint16_t encryption_method; /* encryption method used */ zip_uint32_t flags; /* reserved for future use */ }; The structure pointed to by sb must be allocated before calling zip_stat() or zip_stat_index(). The valid field of the structure specifies which other fields are valid. Check if the flag defined by the following defines are in valid before accessing the fields: ZIP_STAT_NAME name ZIP_STAT_INDEX index ZIP_STAT_SIZE size ZIP_STAT_COMP_SIZE comp_size ZIP_STAT_MTIME mtime ZIP_STAT_CRC crc ZIP_STAT_COMP_METHOD comp_method ZIP_STAT_ENCRYPTION_METHOD encryption_method ZIP_STAT_FLAGS flags
RETURN VALUES
Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in archive is set to indicate the error.
ERRORS
The function zip_stat() can fail for any of the errors specified for the routine zip_name_locate(3). The function zip_stat_index() fails and sets the error information to ZIP_ER_INVAL if index is invalid. If ZIP_FL_UNCHANGED is not set and no information can be obtained from the source callback, the error informa- tion is set to ZIP_ER_CHANGED.
