Detailed Description

String handling utilities.

Function Documentation

spa_streq()

static bool spa_streq ( const char *  s1, const char *  s2  )

inlinestatic

Returns

true if the two strings are equal, false otherwise

If both a and b are NULL, the two are considered equal.

Examples

bluez-session.c, spa/examples/adapter-control.c, spa/examples/example-control.c, spa/examples/local-libcamera.c, and spa/examples/local-v4l2.c.

spa_strneq()

static bool spa_strneq ( const char *  s1, const char *  s2, size_t  len  )

inlinestatic

Returns

true if the two strings are equal, false otherwise

If both a and b are NULL, the two are considered equal.

spa_strstartswith()

static bool spa_strstartswith ( const char *  s, const char *  prefix  )

inlinestatic

Returns

true if s starts with the prefix or false otherwise. A s is NULL, it never starts with the given prefix. A prefix of NULL is a bug in the caller.

spa_strendswith()

static bool spa_strendswith ( const char *  s, const char *  suffix  )

inlinestatic

Returns

true if s ends with the suffix or false otherwise. A s is NULL, it never ends with the given suffix. A suffix of NULL is a bug in the caller.

spa_atoi32()

static bool spa_atoi32 ( const char *  str, int32_t *  val, int  base  )

inlinestatic

Convert str to an int32_t with the given base and store the result in val.

On failure, the value of val is unmodified.

Returns

true on success, false otherwise

spa_atou32()

static bool spa_atou32 ( const char *  str, uint32_t *  val, int  base  )

inlinestatic

Convert str to an uint32_t with the given base and store the result in val.

On failure, the value of val is unmodified.

Returns

true on success, false otherwise

spa_atoi64()

static bool spa_atoi64 ( const char *  str, int64_t *  val, int  base  )

inlinestatic

Convert str to an int64_t with the given base and store the result in val.

On failure, the value of val is unmodified.

Returns

true on success, false otherwise

spa_atou64()

static bool spa_atou64 ( const char *  str, uint64_t *  val, int  base  )

inlinestatic

Convert str to an uint64_t with the given base and store the result in val.

On failure, the value of val is unmodified.

Returns

true on success, false otherwise

spa_atob()

static bool spa_atob ( const char *  str )

inlinestatic

Convert str to a boolean.

Allowed boolean values are "true" and a literal "1", anything else is false.

Returns

true on success, false otherwise

spa_vscnprintf()

static int spa_vscnprintf ( char *  buffer, size_t  size, const char *  format, va_list  args  )

inlinestatic

spa_scnprintf()

static int spa_scnprintf ( char *  buffer, size_t  size, const char *  format,   ...  )

inlinestatic

spa_strtof()

static float spa_strtof ( const char *  str, char **  endptr  )

inlinestatic

Convert str to a float in the C locale.

If endptr is not NULL, a pointer to the character after the last character used in the conversion is stored in the location referenced by endptr.

Returns

the result float.

spa_atof()

static bool spa_atof ( const char *  str, float *  val  )

inlinestatic

Convert str to a float and store the result in val.

On failure, the value of val is unmodified.

Returns

true on success, false otherwise

spa_strtod()

static double spa_strtod ( const char *  str, char **  endptr  )

inlinestatic

Convert str to a double in the C locale.

If endptr is not NULL, a pointer to the character after the last character used in the conversion is stored in the location referenced by endptr.

Returns

the result float.

spa_atod()

static bool spa_atod ( const char *  str, double *  val  )

inlinestatic

Convert str to a double and store the result in val.

On failure, the value of val is unmodified.

Returns

true on success, false otherwise

spa_dtoa()

static char * spa_dtoa ( char *  str, size_t  size, double  val  )

inlinestatic

spa_strbuf_init()

static void spa_strbuf_init ( struct spa_strbuf *  buf, char *  buffer, size_t  maxsize  )

inlinestatic

spa_strbuf_append()

static int spa_strbuf_append ( struct spa_strbuf *  buf, const char *  fmt,   ...  )

inlinestatic
