Flags
indicating whether private fonts, public fonts, or both are required.
These flags can be used in combination:
QFF_PUBLIC
QFF_PRIVATE
pszFaceName (PSZ) - input
Pointer
to a string specifying the face name.
When this is NULL, all faces are matched.
paMetrics (PFONTMETRICS) -
input
Pointer to an array of font element records
to which the metrics of matching fonts are returned. This is a pointer to
an array of up to cFontCount font metric records, each of which contains
a maximum of cMetricLen bytes. Note that for multi-codepage fonts the usCodePage
field has no meaning and is set to 0.
cMetricLen (ULONG) - input
Length
in bytes of each metrics structure in the paMetrics array.
pcFontCount (PULONG) - input
Pointer
to cFontCount that specifies the number of fonts for which metrics are required.
On return, this is updated to the number of fonts for which metrics were
returned.
pInstance (PVOID) - input
Pointer
to instance data.
lFunction (ULONG) - input
High-order
WORD=flags; low-order WORD=NGreQueryFonts.
rc (LONG) - returns
Return
codes.
This function returns the number of fonts not returned, or it returns GPI_ALTERROR
if an error occurs.
Possible Errors Detected: When an error is detected, the graphics
engine calls WinSetErrorInfo to post the condition. Reasons for failure
of this function include:
PMERR_COORDINATE_OVERFLOW PMERR_DEV_FUNC_NOT_INSTALLED
PMERR_HDC_BUSY
PMERR_INV_COORD_SPACE
PMERR_INV_HDC
PMERR_INV_LENGTH_OR_COUNT
PMERR_INV_OR_INCOMPAT_OPTIONS

Explanations" section of the Presentation Manager Programming Reference
for further explanation.
