NAME btree – btree database access method SYNOPSIS #include <db.h> #include <sys/types.h> DESCRIPTION Note well: This page documents interfaces provided in glibc up until version 2.1. Since version 2.2, glibc no longer provides these interfaces. Probably, you are looking for the APIs provided by the libdb library instead. The routine dbopen(3) is the library interface…
NAME btowc – convert single byte to wide character SYNOPSIS #include <wchar.h> wint_t btowc(int c); DESCRIPTION The btowc() function converts c, interpreted as a multibyte sequence of length 1, starting in the initial shift state, to a wide character and returns it. If c is EOF or not a valid multibyte sequence of length 1,…

NAME bson_zero_free() – This function behaves like bson_free() except that it zeroes the memory first. This can be useful if you are storing passwords or other similarly important data. Note that if it truly is important, you probably want a page protected with mlock() as well to prevent it swapping to disk. SYNOPSIS void bson_zero_free(void…
NAME bson_writer_t – Bulk BSON serialization Abstraction SYNOPSIS #include <bson.h> typedef struct _bson_writer_t bson_writer_t; bson_writer_t *bson_writer_new(uint8_t **buf, size_t *buflen, size_t offset, bson_realloc_func realloc_func, void *realloc_func_ctx); void bson_writer_destroy(bson_writer_t *writer); DESCRIPTION The bson_writer_t API provides an abstraction for serializing many BSON documents to a single memory region. The memory region may be dynamically allocated and re-allocated as…
NAME bson_writer_rollback() – Abort the appending of the current bson_t to the memory region managed by writer. This is useful if you detected that you went past a particular memory limit. For example, MongoDB has 48MB message limits. SYNOPSIS void bson_writer_rollback(bson_writer_t *writer); PARAMETERS writer A bson_writer_t \&. DESCRIPTION Abort the appending of the current bson_t…
