# NAME

`sqlite3_blob_bytes` —
Return 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.
