NAME

zip_source_stat — get information about zip_source

LIBRARY

libzip (-lzip)

SYNOPSIS

#include <zip.h>

int

zip_source_stat(zip_source_t *source, zip_stat_t *sb);

DESCRIPTION

The zip_source_stat() function obtains information about the zip source source

The sb argument is a pointer to a struct zip_source_stat (shown below), into which information about the zip source is placed.

struct zip_source_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 initialized with zip_stat_init(3) before calling zip_source_stat().

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

NOTE: Some fields may only be filled out after all data has been read from the source, for example the crc or size fields.

RETURN VALUES

Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in source is set to indicate the error.
