Functions

int  av_strstart (const char *str, const char *pfx, const char **ptr)

  Return non-zero if pfx is a prefix of str.

 

int  av_stristart (const char *str, const char *pfx, const char **ptr)

  Return non-zero if pfx is a prefix of str independent of case.

 

char *  av_stristr (const char *haystack, const char *needle)

  Locate the first case-independent occurrence in the string haystack of the string needle.

 

char *  av_strnstr (const char *haystack, const char *needle, size_t hay_length)

  Locate the first occurrence of the string needle in the string haystack where not more than hay_length characters are searched.

 

size_t  av_strlcpy (char *dst, const char *src, size_t size)
