## Functions
EVIL_API char * | strcasestr (const char *haystack, const char *needle)
| Locate a substring into a string, ignoring case.
EVIL_API char * | strsep (char **stringp, const char *delim)
| Implements the strsep function which is used to separate strings.

## Detailed Description

This header provides functions ported from Unix in string.h.

## Function Documentation

## ◆ strcasestr()

EVIL_API char * strcasestr | ( | const char * | haystack,
|  | const char * | needle
| ) |  |

Locate a substring into a string, ignoring case.

Parameters

  haystack | The string to search in.
  needle | The substring to find.

Returns

This function locates the string `needle` into the string `haystack`, ignoring the case of the characters. It returns apointer to the beginning of the substring, or NULL if the substring is not found. If `haystack` or `needle` are `NULL`, this function returns `NULL`.

Conformity: Non applicable.

Supported OS: Windows XP.

## ◆ strsep()

EVIL_API char * strsep | ( | char ** | stringp,
|  | const char * | delim
| ) |  |

Implements the strsep function which is used to separate strings.

Parameters

  stringp | The pointer to the string to search in.
  delim | The delimiter that contains characters used to find the next token.

Returns
  a pointer to the next token or NULL;

The strsep() function locates, in the string referenced by *stringp, the first occurrence of any character in the string delim (or the terminating ‘\0’ character) and replaces it with a ‘\0’. The location of the next character after the delimiter character (or NULL, if the end of the string was reached) is stored in *stringp. The original value of stringp is returned.

An `‘empty’' field (i.e., a character in the string delim occurs as the first character of *stringp) can be detected by comparing the location referenced by the returned pointer to ‘\0’.

If *stringp is initially NULL, strsep() returns NULL.

This function is from LibGW32C.
