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)
	Copy the string src to dst, but no more than size - 1 bytes, and null-terminate dst.
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.
size_t	av_strlcatf (char *dst, size_t size, const char *fmt,...) av_printf_format(3
	Append output to a string, according to a format.
size_t static size_t	av_strnlen (const char *s, size_t len)
	Get the count of continuous non zero chars starting from the beginning.
char *	av_asprintf (const char *fmt,...) av_printf_format(1
	Print arguments following specified format into a large enough auto allocated buffer.
char char *	av_d2str (double d)
	Convert a number to a av_malloced string.
char *	av_get_token (const char **buf, const char *term)
	Unescape the given string until a non escaped terminating char, and return the token corresponding to the unescaped string.
char *	av_strtok (char *s, const char *delim, char **saveptr)
	Split the string into several tokens which can be accessed by successive calls to av_strtok().
int	av_isdigit (int c)
	Locale-independent conversion of ASCII isdigit.
int	av_isgraph (int c)
	Locale-independent conversion of ASCII isgraph.
int	av_isspace (int c)
	Locale-independent conversion of ASCII isspace.
static int	av_toupper (int c)
	Locale-independent conversion of ASCII characters to uppercase.
static int	av_tolower (int c)
	Locale-independent conversion of ASCII characters to lowercase.
int	av_isxdigit (int c)
	Locale-independent conversion of ASCII isxdigit.
int	av_strcasecmp (const char *a, const char *b)
	Locale-independent case-insensitive compare.
int	av_strncasecmp (const char *a, const char *b, size_t n)
	Locale-independent case-insensitive compare.
const char *	av_basename (const char *path)
	Thread safe basename.
const char *	av_dirname (char *path)
	Thread safe dirname.
int	av_escape (char **dst, const char *src, const char *special_chars, enum AVEscapeMode mode, int flags)
	Escape string in src, and put the escaped string in an allocated string in *dst, which must be freed with av_free().
int	av_utf8_decode (int32_t *codep, const uint8_t **bufp, const uint8_t *buf_end, unsigned int flags)
	Read and decode a single UTF-8 code point (character) from the buffer in *buf, and update *buf to point to the next byte to decode.
