#define AV_ESCAPE_FLAG_WHITESPACE   0x01

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 char * av_asprintf (const char *fmt,...) av_printf_format(1
 Print arguments following specified format into a large enough auto allocated buffer.
 
size_t 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().
