## NAME

libssh2\_sftp\_unlink\_ex - unlink an SFTP file

## SYNOPSIS

```
#include <libssh2.h>
#include <libssh2_sftp.h>
int
libssh2_sftp_unlink_ex(LIBSSH2_SFTP *sftp, const char *filename, unsigned int filename_len);
int
libssh2_sftp_unlink(LIBSSH2_SFTP *sftp, const char *filename);
```

*LIBSSH2\_ERROR\_SOCKET\_TIMEOUT* -
