ftp_ffind

#include <net_config.h>

U16 ftp_ffind (
    U8  code,      /* Function request code. */
    U8* buf,       /* Pointer to the buffer to write to. */
    U8* mask,      /* Pattern to match files to. */
    U16 buflen );  /* Length of the output buffer. */

The ftp_ffind function searches the File System directory for files matching the specified mask filter. Matching file information is stored to the output buffer specified with buf. The output data must be formatted in the FTP folder listing format.

Parameter code specifies the request type for the ftp_ffind function.

Parameter buflen specifies the size of output buffer buf.

The ftp_ffind function is in the FTP_uif.c module. The prototype is defined in net_config.h.

The ftp_ffind function returns the number of bytes written to the buf.
