Functions
int	av_strstart (const char *str, const char *pfx, const char **ptr)
	Return non-zero if pfx is a prefix of str. More...
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. More...
char *	av_stristr (const char *haystack, const char *needle)
	Locate the first case-independent occurrence in the string haystack of the string needle. More...
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. More...
size_t	av_strlcpy (char *dst, const char *src, size_t size)
	Copy the string src to dst, but no more than size - 1 bytes, and null-terminate dst. More...
size_t	av_strlcat (char *dst, const char *src, size_t size)
	Append the string src to the string dst, but to a total length of no more than size - 1 bytes, and null-terminate dst. More...

char char *	av_d2str (double d)
	Convert a number to an av_malloced string. More...
char *	av_get_token (const char **buf, const char *term)
