PWRZT – Draws the projections of character strings that are positioned in a plane parallel to one of the three coordinate planes. NOTE: At one time, a Threed routine called PWRZ was supported. PWRZ has been superseded by PWRZT and is therefore considered obsolete. If you call PWRZ, you will get an error message telling…
PWRITY – draws text and other characters using polylines. Utility This routine is part of the Pwrite_family utility in NCAR Graphics. To see the overview man page for this utility, type "man pwrite_family". Status PWRITY is obsolete. It has been replaced by the PLCHHQ, PLCHMQ, and PLCHLQ entries of the Plotchar utility. PWRITY continues to…
PWRITX – draws text and other characters using polylines. Utility This routine is part of the Pwrite_family utility in NCAR Graphics. To see the overview man page for this utility, type "man pwrite_family". Status PWRITX is obsolete. It has been replaced by the PLCHHQ, PLCHMQ, and PLCHLQ entries of the Plotchar utility. PWRITX continues to…
Pwrite_family – A utility for drawing text and other characters using polylines. Status Pwrite_family is obsolete. It has been replaced by the Plotchar utility. Entries PWRITX and PWRITY continue to be provided for compatibility of early NCAR Graphics codes. If you are writing new code, we suggest that you use Plotchar. Synopsis PWRITX (X,Y,IDPC,NCHAR,JSIZE,JOR,JCTR) –…
PWRIT – draws a specified text string at a specified position in the user coordinate system. The call has arguments specifying the size, orientation, and centering of the string. Status PWRIT is an earlier version of the routine WTSTR in which the number of characters in the text string was specified in an argument. Both…
PWRZT – Draws the projections of character strings that are positioned in a plane parallel to one of the three coordinate planes. NOTE: At one time, a Threed routine called PSYM3 was supported. It has long been considered obsolete. If you call PSYM3, you will get an error message telling you to use PWRZT instead…
mongoc_stream_write() – The mongoc_stream_write() function shall perform a write to a mongoc_stream_t. It’s modeled on the API and semantics of write(), though the parameters map only loosely. Synopsis ssize_t mongoc_stream_write (mongoc_stream_t *stream, void *buf, size_t count, int32_t timeout_msec); Parameters stream A mongoc_stream_t \&. buf The buffer to write. count The number of bytes to write….
mongoc_collection_remove() – This function shall remove documents in the given collection that match selector. The bson selector is not validated, simply passed along as appropriate to the server. As such, compatibility and errors should be validated in the appropriate server documentation. Synopsis bool mongoc_collection_remove (mongoc_collection_t *collection, mongoc_remove_flags_t flags, const bson_t *selector, const mongoc_write_concern_t *write_concern, bson_error_t…
mongoc_collection_keys_to_index_string() – This function shall returns the canonical stringification, as used in mongoc_collection_create_index() without an explicit name, of a given key specification. Synopsis char * mongoc_collection_keys_to_index_string (const bson_t *keys); Parameters keys A bson_t \&. Description This function shall returns the canonical stringification, as used in mongoc_collection_create_index(3) without an explicit name, of a given key specification….
mongoc_client_get_database() – None Synopsis mongoc_database_t * mongoc_client_get_database (mongoc_client_t *client, const char *name); Get a newly allocated mongoc_database_t for the database named name \&. NOTE Databases are automatically created on the MongoDB server upon insertion of the first document into a collection. There is no need to create a database manually. Parameters client A mongoc_client_t \&….
mongoc_client_get_collection() – None Synopsis mongoc_collection_t * mongoc_client_get_collection (mongoc_client_t *client, const char *db, const char *collection); Get a newly allocated mongoc_collection_t for the collection named collection in the database named db \&.

mongoc_client_destroy() – None Synopsis void mongoc_client_destroy (mongoc_client_t *client); Release all resources associated with client and free the structure. Parameters client A mongoc_client_t \&. Colophon This page is part of MongoDB C Driver. Please report any bugs at https://jira.mongodb.org/browse/CDRIVER.
