## Function Documentation

void print_tty_input_seq | ( | void |  | ) |

Print a line to stdout that asks for an input sequence.

There will also be a ruler (scale line) printed that helps orientation of the sequence positions

Deprecated:
  Use vrna_message_input_seq_simple() instead!

void print_tty_input_seq_str | ( | const char * | s | ) |

Print a line with a user defined string and a ruler to stdout.

(usually this is used to ask for user input) There will also be a ruler (scale line) printed that helps orientation of the sequence positions

Deprecated:
  Use vrna_message_input_seq() instead!

void warn_user | ( | const char | message[] | ) |

Print a warning message.

Print a warning message to stderr

Deprecated:
  Use vrna_message_warning() instead!

void nrerror | ( | const char | message[] | ) |

Die with an error message.

Deprecated:
  Use vrna_message_error() instead!

void* space | ( | unsigned | size | ) |

Allocate space safely.

Deprecated:
  Use vrna_alloc() instead!

void* xrealloc | ( | void * | p,
|  | unsigned | size
| ) |  |

Reallocate space safely.

Deprecated:
  Use vrna_realloc() instead!

void init_rand | ( | void |  | ) |

Make random number seeds.

Deprecated:
  Use vrna_init_rand() instead!

double urn | ( | void |  | ) |

get a random number from [0..1]

Deprecated:
  Use vrna_urn() instead!

int int_urn | ( | int | from,
|  | int | to
| ) |  |

Generates a pseudo random integer in a specified range.

Deprecated:
  Use vrna_int_urn() instead!

void filecopy | ( | FILE * | from,
|  | FILE * | to
| ) |  |

Inefficient `cp`

Deprecated:
  Use vrna_file_copy() instead!

char* time_stamp | ( | void |  | ) |

Get a timestamp.

Deprecated:
  Use vrna_time_stamp() instead!
