我使用ar.h来定义结构.我想知道如何获取有关文件的信息并将其放入结构中的指定变量中.
struct ar_hdr {
char ar_name[16]; /* name of this member */
char ar_date[12]; /* file mtime */
char ar_uid[6]; /* owner uid; printed as decimal */
char ar_gid[6]; /* owner gid; printed as decimal */
char ar_mode[8]; /* file mode, printed as octal */
char ar_size[10]; /* file size, printed as decimal */
char ar_fmag[2]; /* should contain ARFMAG */
};
使用上面定义的结构,我将如何从文件中获取信息 ls -la
