rc_config_value(3)

NAME

rc_config_list, rc_config_load, rc_config_value, rc_yesno — functions to query OpenRC service configurations

LIBRARY

Run Command library (librc, -lrc)

SYNOPSIS

#include <rc.h>

RC_STRINGLIST *
rc_config_list(const char *file);

RC_STRINGLIST *
rc_config_load(const char *file);

char *
rc_config_value(const char *const *list, const char *entry);

bool
rc_yesno(const char *value);

DESCRIPTION

These functions provide an easy means of querying OpenRC configuration files.

rc_config_list() returns a list of non comment lines in file. rc_config_load() does the same, but attempts to parse the line as if it was a shell assignment. rc_config_value() returns the value of entry found in list.

Each list should be freed using rc_stringlist_free() when done.

rc_yesno() returns true if value is "true", "yes", "y" or "1" regardless of case. Otherwise if value is "false", "no", "n" or "0" (regardless of case) returns false. If value does not match either, then returns false and sets errno to EINVAL.
