## Function Documentation

## ◆ fcntl()

EVIL_API int fcntl | ( | int | fd,
|  | int | cmd,
|  |  | ...
| ) |  |

Provide control over file descriptors.

Parameters

  fd | The file descriptor.
  cmd | The type of control.

Returns
  0 on success, -1 otherwise.

Performs one of various miscellaneous operations on `fd`. The operation in question is determined by `cmd:`

- F_SETFD: Set the close-on-exec flag to the value specified by the argument after command (only the least significant bit is used).
- F_SETLK and F_SETLKW: used to manage discretionary file locks. The third argument must be a pointer to a struct flock (that may be overwritten by this call).

This function returns 0 on success, -1 otherwise.

Conformity: None.

Supported OS: Windows Vista, Windows XP or Windows 2000 Professional.

References flock::l_len, flock::l_start, flock::l_type, and flock::l_whence.

## ◆ evil_char_to_wchar()

EVIL_API wchar_t* evil_char_to_wchar | ( | const char * | text | ) |

Convert a string from char * to wchar_t *.

Parameters

  text | The string to convert.

Returns
  The converted string.

Convert a string from char * to wchar_t * and return it. If the allocation or conversion fails, NULL is returned. On success, the returned value must be freed when it is not used anymore.

Conformity: Non applicable.

Supported OS: Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, Windows XP.

## ◆ evil_wchar_to_char()

EVIL_API char* evil_wchar_to_char | ( | const wchar_t * | text | ) |

Convert a string from wchar_t * to char *.

Parameters

  text | The string to convert.

Returns
  The converted string.

Convert a string from wchar_t * to char * and return it. If the allocation or conversion fails, NULL is returned. On success, the returned value must be freed when it is not used anymore.

Conformity: Non applicable.

Supported OS: Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, Windows XP.

## ◆ evil_utf16_to_utf8()

EVIL_API char* evil_utf16_to_utf8 | ( | const wchar_t * | text | ) |

Convert a string from UTF-16 to UTF-8.

Parameters

  text | The string to convert in UTF-16.

Returns
  The converted string in UTF-8.

Convert a string from UTF-16 to UTF-8 and return it. If the allocation or conversion fails, NULL is returned. On success, the returned value must be freed when it is not used anymore.

Conformity: Non applicable.

Supported OS: Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, Windows XP.

## ◆ evil_utf8_to_utf16()

EVIL_API wchar_t* evil_utf8_to_utf16 | ( | const char * | text | ) |

Convert a string from UTF-8 to UTF-16.

Parameters

  text | The string to convert in UTF-8.

Returns
  The converted string in UTF-16.

Convert a string from UTF-8 to UTF-16 and return it. If the allocation or conversion fails, NULL is returned. On success, the returned value must be freed when it is not used anymore.

Conformity: Non applicable.

## ◆ evil_path_is_absolute()

EVIL_API int evil_path_is_absolute | ( | const char * | path | ) |

check if the given path is absolute.

Parameters

  path | The path to check.

Returns
  1 if the given path is absolute, 0 otherwise.

Check if the path `path` is absolute or not. An absolute path must begin with a letter (upper or lower case), followed by by the char ':', followed by the char '/' or '\'. If `path` is absolute this function returns 1, otherwise it returns 0. If `path` is `NULL`, it returns 0.

Conformity: Non applicable.

Supported OS: Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, Windows XP.
