◆ econf_setValue

#define econf_setValue (   kf,
  group,
  key,
  value 
)
Value:
(( \
_Generic((value), \
unsigned int: econf_setUIntValue, \
unsigned long: econf_setUInt64Value, \
(kf, group, key, value))
econf_err econf_setUInt64Value(econf_file *kf, const char *group, const char *key, uint64_t value)
Set uint64 value for given group/key.
econf_err econf_setDoubleValue(econf_file *kf, const char *group, const char *key, double value)
Set double value for given group/key.
econf_err econf_setInt64Value(econf_file *kf, const char *group, const char *key, int64_t value)
Set int64 value for given group/key.
econf_err econf_setUIntValue(econf_file *kf, const char *group, const char *key, uint32_t value)
Set uint32 value for given group/key.
econf_err econf_setStringValue(econf_file *kf, const char *group, const char *key, const char *value)
Set string value for given group/key.
econf_err econf_setFloatValue(econf_file *kf, const char *group, const char *key, float value)
Set float value for given group/key.
econf_err econf_setIntValue(econf_file *kf, const char *group, const char *key, int32_t value)
Set int32 value for given group/key.

Generic macro calls setter function depending on value type.

Use: econf_setValue(econf_file *key_file, char *group, char *key, generic value);

Replace generic with one of the supported value types. Supported Types: int, long, unsigned int, unsigned long, float, double, string (as *char). Note: Does not detect "yes", "no", 1 and 0 as boolean type. If you want to set a bool value use "true" or "false" or use setBoolValue() directly.
