# 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.
