status = PMDFaddHeaderLine

(header, type, line, line_len)

argument information

int PMDFaddHeaderLine(PMDF_hdr **header, int type, char *line, int line_len)

Arguments

header

Address of a header structure.

type

The type of header line being added.

line

The header line to add. No length limit is imposed.

line_len

The length in bytes of line.

Description

PMDFaddHeaderLine adds a header line of the specified type to the header structure, header. The header structure need not have been created by a previous call to PMDFreadHeader ; PMDFaddHeaderLine will initialize the structure if it is nil (zero) on input. The type argument specifies the type of header line being added (e.g., HL_FROM, HL_TO, HL_DATE, etc.). The accepted types are defined in the API include files; see Section 1.6 for further details. Specify HL_OTHER for a header line type not recognized by the API. Only the body of the header line must be specified in the line argument. The field name and colon and space will be prepended to what you specify. For example, if you specify HL_X_YOW in the type argument, and the string "Wow! PMDF is great!" in the line argument, this routine will add the following header: "X-Yow: Wow! PMDF is great!". Header structures can be output with PMDFwriteHeader and disposed of with PMDFdisposeHeader . See Section 1.6 for further details on using and manipulating header structures.

Return Values

PMDF__OK	Normal, successful completion.
PMDF__HEANOTKNW	Unknown header line type. No header line added. Recall PMDFaddHeaderLine specifying HL_OTHER for the header line type.
PMDF__INVSTRDES	Invalid string descriptor for line: descriptor has an invalid value in its DSC$B_CLASS field. No header line added.
