.SH "NAME"
tep_event_common_fields, tep_event_fields \- Get a list of fields for an event\&.
.SH "SYNOPSIS"
.sp
.nf
\fB#include <event\-parse\&.h>\fR

struct tep_format_field **\fBtep_event_common_fields\fR(struct tep_event *\fIevent\fR);
struct tep_format_field **\fBtep_event_fields\fR(struct tep_event *\fIevent\fR);
.fi
.SH "DESCRIPTION"
.sp
The \fItep_event_common_fields()\fR function returns an array of pointers to common fields for the \fIevent\fR\&. The array is allocated in the function and must be freed by free()\&. The last element of the array is NULL\&.
.sp
The \fItep_event_fields()\fR function returns an array of pointers to event specific fields for the \fIevent\fR\&. The array is allocated in the function and must be freed by free()\&. The last element of the array is NULL\&.
.SH "RETURN VALUE"
.sp
Both \fItep_event_common_fields()\fR and \fItep_event_fields()\fR functions return an array of pointers to tep_format_field structures in case of success, or NULL in case of an error\&.
