  35. .SH NAME
  36. confdb_key_replace \- Replace a key/value pair from the Configuration Database
  37. .SH SYNOPSIS
  38. .B #include <corosync/confdb.h>
  39. .sp
  40. .BI "confdb_error_t confdb_key_replace(confdb_handle_t " handle ", unsigned int " parent_object_handle ", void " *key_name ",
  41. .BI int " key_name_len ",
  42. .BI void " *old_value ",
  43. .BI int " old_value_len ",
  44. .BI void " *new_value ",
  45. .BI int " new_value_len "); "
  46. .SH DESCRIPTION
  47. The
  48. .B confdb_key_replace
  49. function replaces the value of a key in the configuration database.
  50. .br
  51. You must specify both the key name and its value, this is because keys are not
  52. unique in the database, so a value is not enough to uniqely identify a key belonging
  53. to a particular parent object.
  54. .BR
  55. Strictly, even give the key name and value is not enough to uniquely identify a key,
  56. If there are two (or more) keys with the same name and value, only the first will have
  57. its value changed .
  58. .SH RETURN VALUE
  59. This call returns the CONFDB_OK value if successful, otherwise an error is returned.
  60. .PP
  61. .SH ERRORS
  62. The errors are undocumented.
