SQLITE3_BLOB_BYTES(3) Library Functions Manual SQLITE3_BLOB_BYTES(3)

NAME

sqlite3_blob_bytesReturn The Size Of An Open BLOB

SYNOPSIS

int
sqlite3_blob_bytes(sqlite3_blob *);

DESCRIPTION

Returns the size in bytes of the BLOB accessible via the successfully opened BLOB handle in its only argument. The incremental blob I/O routines can only read or overwriting existing blob content; they cannot change the size of a blob.
This routine only works on a BLOB handle which has been created by a prior successful call to sqlite3_blob_open() and which has not been closed by sqlite3_blob_close(). Passing any other pointer in to this routine results in undefined and probably undesirable behavior.
