SYS_FS_RESULT SYS_FS_FileStringGet
(
    SYS_FS_HANDLE handle,
    char* buff,
    uint32_t len
);

Reads a string from the file into a buffer.

This function reads a string of specified length from the file into a buffer. The read operation continues until:

• '\n' is stored

• reached end of the file or

• the buffer is filled with len - 1 characters. The read string is terminated with a '\0'.

The file from which a string has to be read, has to be present and should have been opened.

SYS_FS_RES_SUCCESS - String read operation was successful.

SYS_FS_RES_FAILURE - String read operation was unsuccessful. The reason for the failure can be retrieved with SYS_FS_Error or SYS_FS_FileError.
