SYNOPSIS

9          #include <opensc.h>
10
11          int sc_write_record(struct sc_card *card, unsigned int record,
12                              const unsigned char *buf, size_t buflen,
13                              unsigned long flags);

DESCRIPTION

18       This function writes a record that is buflen bytes long from the buffer
19       pointed to by buf to a record-structured elementary file (EF) on card.
20       The function corresponds to the ISO 7816 WRITE RECORD function. Call
21       sc_select_file() first to select the file to write to.
22
23       record specifies the ID of the record to be written, or, if flags is
24       set to SC_RECORD_BY_REC_NR, the record number. If record is set to
25       zero, the current record will be read.
26
27       This function is used for newly created files only; for updating or
28       appending to existing files, see the sc_update_record() and
29       sc_append_record() functions, respectively.

RETURN VALUE

32       Returns the number of bytes written if successful, or a negative value
33       in case of error.
