Berkeley DB: memp_fclose
Полезная информация


#include <db.h>

int memp_fclose(DB_MPOOLFILE *mpf);


The memp_fclose function closes the source file indicated by the DB_MPOOLFILE structure. Calling memp_fclose does not imply a call to memp_fsync, i.e. no pages are written to the source file as as a result of calling memp_fclose.

In addition, if the file argument to memp_fopen was NULL, any underlying files created for this DB_MPOOLFILE will be removed.

The memp_fclose function returns the value of errno on failure, and 0 on success.


If a fatal error occurs in Berkeley DB, the memp_fclose function may fail and return DB_RUNRECOVERY, at which point all subsequent database calls will also return DB_RUNRECOVERY.

The memp_fclose function may fail and return errno for any of the errors specified for the following Berkeley DB and C library functions: abort(3), close(3), fcntl(3), fflush(3), fprintf(3), free(3), getpid(3), memset(3), munmap(3), strerror(3), vfprintf(3), and vsnprintf(3).
