## 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_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().

av_warn_unused_result 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().
av_warn_unused_result int | av_utf8_decode (int32_t *codep, const uint8_t **bufp, const uint8_t *buf_end, unsigned int flags)
