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_NAMEnameZIP_STAT_INDEXindexZIP_STAT_SIZEsizeZIP_STAT_COMP_SIZEcomp_sizeZIP_STAT_MTIMEmtimeZIP_STAT_CRCcrcZIP_STAT_COMP_METHODcomp_methodZIP_STAT_ENCRYPTION_METHODencryption_methodZIP_STAT_FLAGSflags

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.

HISTORY

zip_source_stat() was added in libzip 1.0.
